▼ A critical part of clinical trials in drug development is the analysis of treatment efficacy in patient subgroups (subpopulations). Due to multiplicity and the small sample sizes involved, this analysis presents substantial statistical challenges and can lead to misleading conclusions. In this thesis, we develop methodology for statistically valid subgroup analysis in a variety of settings. First, we consider a number of trial designs of varying flexibility for the case of one subgroup of interest. Some procedures are novel, while others are adapted from the literature. Included is data-driven consideration of adaptive change of subject eligibility criteria-known as adaptive enrichment-whereby apparently nonresponsive patient populations are not recruited after data has been unblinded for an interim analysis. We conduct an extensive numerical study to investigate design operating characteristics, as well as sensitivity to subgroup prevalence and interim analysis timing. We observe that power gains can be substantial when a treatment is only effective in the subgroup of interest. Following this example, selected procedures are generalized to allow for analysis of an arbitrary number of subgroups. Next, we propose a K -stage group sequential design that can be applied as a confirmatory seamless Phase II/III design. The design is specified through upper and lower spending functions, defined in terms of calendar times. After the first stage, poorly performing subgroups are eliminated and the remaining population is pooled for the duration of the trial. This procedure combines the elimination of non-sensitive subgroups with the definitive assessment of treatment efficacy associated with traditional group sequential designs. Numerical examples show that the procedure has high power to detect subgroup-specific effects, and the use of multiple interim analysis points can lead to substantial sample size savings. We address the challenges of adjusting for selection bias, and protecting the familywise error rate in the strong sense. All designs are presented either in terms of standardized test statistics or the efficient score, making the analysis of normal, binary, or time-to-event data straightforward.

Multiple comparison procedures are used to compare factor levels means. Nevertheless the most popular tests show problems concerning the ambiguity of results and the control of type I error, some of which were considered conservative and other liberal. Methods based on cluster analysis have been proposed to avoid ambiguity. The present work aims to propose a bootstrap alternative to one of Caliński &Corsten (1985) multiple comparison procedures based on cluster analysis and evaluate the original and bootstrap tests by Monte Carlo simulation considering normal and non-normal probabilistic models. The methodology by Caliński &Corsten (1985) uses the extension of a simultaneous test based on studentized range. N=1000 simulations of k unstructured and qualitative populations were considered. In each simulation r sample sizes (4, 10 e 20) of each of the k populations (5, 10, 20 e 80) (factor levels) were generated. The probabilistic models exponencial, lognormal and normal were considered for the populations. Under complete H0 there were no factor effects. Thus the factorÂs levels presented common mean and common variance. Under partial H0 situation it was considered two groups for which the procedure used for H0 complete is applied. The densities between the groups had different values for the parameters. Under H1 the densities were considered all different. In the normal case they differentiate themselves only for the mean Â, maintaining variance σ2 constant. The two methods were applied in all the simulated configurations. In the N experiments generated from each one of them the performance was evaluated in relation to the type I error rates per experiment (under complete and partial H0 situations) and in relation to the power (under partial H0 and H1 situations). The normal distribution situation was used as suitable environment due to the fact that the Caliński &Corsten test was idealized under the assumption of normality. The simulation software was implemented in R. Thus, it could be concluded that the two tests are exact under complete H0 and normality; under non-normality and complete H0 the bootstrap test controls the type I error per experiment and it is robust; under non-normality and complete H0 the original test is conservative for small values of k and it is liberal for great values of k; in general, under partial H0 situation, the two tests are liberal for smaller differences between groups and they are conservative for greater differences; the power of bootstrap test is considered higher than the original test under partial H0 and H1; in general, the bootstrap test performance is considered robust and superior to the original test being, therefore, recommended.

▼ Measuring high-dimensional dependence is a difficult and important problem in the fields of statistics and machine learning, and is often being used for applications in biostatistics. In this dissertation, the effect of kernel methods are studied for high dimensional measure of dependence, and the methods are applied to neuroimaging data from the Alzheimer's Disease Neuroimaging Initiative (ADNI) study. The ADNI study is a comprehensive dataset with the goal of finding potential genetic variants that contribute to the difference in brain volumes among the subjects, it contains brain magnetic resonance image (MRI) scans of 741 enrolled subjects, and are the main neuroimaging data used for this work. The first part of this dissertation utilizes distance covariance for the association analysis on the ADNI dataset, as distance covariance is a consistent test and is able to identify linear or non-linear associations, and also preserve the within variable interactions using the L₂ distance kernel. Furthermore, combining distance covariance with a novel FDR modeling algorithm is proposed for examining a larger number of genetic variants simultaneously and it results in an increase number of significant findings than what has been seen previously in the literature. The association analysis is then extended to the cases when covariates are present, where distance covariance is discussed in Hilbert spaces that results in a new representation called the kernel distance covariance (KDC). As part of our explorations under Hilbert spaces, we find and establish the equivalence of KDC and kernel machine regression (KMR) under certain conditions, and this leads to two major contributions: 1) the equivalence allows to measure the associations between two variables while taking into accounts of the covariate effects; and 2) KMR is found to be a member of KDC, where the family members are the different input kernels. This framework that unifies KDC and KMR leads to the problem of finding the optimal kernel pair among the KDC family, and is the concluding part of this work. For finding the optimal kernel pair, we emphasize the discussion under the situations that there be no covariate effects, under which the KDC is related to the Hilbert-Schmidt Independence Criterion (HSIC). A local-alternative Power Maximization algorithm (LaPM) is proposed for the search of kernel pair optimality at a given test level, where LaPM selects the best kernel pair which maximizes the test power against local alternative (the Pitman approach). The numerical analysis shows that LaPM is able to achieve higher power than other existing approaches, and our real data experiment using the ADNI study shows that the optimal kernel pair selected by the proposed method can be used for the interpretation of high dimensional data.

▼ The current research examined the role of framing and direction in health social comparisons by multiple sclerosis patients. Framing refers to whether the self is considered similar (identified), or different (contrasted), to a comparison target. Direction is whether the target is doing better (upward), or worse (downward), than the self. Positive, negative and neutral emotional responses (Study 1 and 2), and coping responses (Study 2), via the brief COPE (Carver, 1997), to different types of social comparisons were examined. The role of personality within social comparisons was also assessed as past research has not systematically examined personality within the comparison process. Five personality variables (neuroticism, self-esteem, optimism, internal health control, and social comparison orientation (SCO), were examined in Study 1 and 2. Neuroticism, self-esteem and optimism were found to assess the same underlying construct and so were combined to form a Negative Affective Style variable.; Study 1 employed a within-subjects 2 (Comparison Frame: identified vs. contrasted) x 2 (Comparison Direction: upward vs. downward) design to examine emotional responses to recalled social comparisons. Study 2 examined the same two variables, comparison frame and direction, in a 2 x 2 between-subjects design. Study 2 however, employed a standardized scenario where participants imagined hypothetical social comparisons.; Interaction effects of comparison frame and direction were found on emotions in both Study 1 and Study 2. Comparison frame systematically moderated the effect of comparison direction on emotional responses. Furthermore, the nature of this interaction differed dependent on emotion (e.g. anger vs. fear). Surprisingly though, only comparison frame was found to predict coping, specifically, Active coping.; Across both studies participants with high internal health control reported more positive emotions in response to comparisons. Additionally, participants high in SCO and negative affective style reported more negative emotional responses to comparisons. A sixth personality variable, social desirability, was measured only in Study 2 where higher social desirability predicted less negative emotions in response to comparisons.; Finally, the results of Study 1 showed that across different targets participants preferred to make downward comparisons that contrast the self to the target.

▼ Decision making is an essential activity for humans and often becomes complex in the presence of uncertainty or insufficient knowledge. This research aims at estimating preferences using pairwise comparisons. A decision maker uses pairwise comparison when he/she is unable to directly assign criteria weights or scores to the available options. The judgments provided in pairwise comparisons may not always be consistent for several reasons. Experimentation has been used to obtain statistical evidence related to the widely-used consistency measures. The results highlight the need to propose new consistency measures. Two new consistency measures - termed congruence and dissonance - are proposed to aid the decision maker in the process of elicitation. Inconsistencies in pairwise comparisons are of two types i.e. cardinal and ordinal. It is shown that both cardinal and ordinal consistency can be improved with the help of these two measures. A heuristic method is then devised to detect and remove intransitive judgments. The results suggest that the devised method is feasible for improving ordinal consistency and is computationally more efficient than the optimization-based methods. There exist situations when revision of judgments is not allowed and prioritization is required without attempting to remove inconsistency. A new prioritization method has been proposed using the graph-theoretic approach. Although the performance of the proposed prioritization method was found to be comparable to other approaches, it has practical limitation in terms of computation time. As a consequence, the problem of prioritization is explored as an optimization problem. A new method based on multi-objective optimization is formulated that offers multiple non-dominated solutions and outperforms all other relevant methods for inconsistent set of judgments. A priority estimation tool (PriEsT) has been developed that implements the proposed consistency measures and prioritization methods. In order to show the benefits of PriEsT, a case study involving Telecom infrastructure selection is presented.

▼ A number of multiple comparison procedures (MCPs) have been studied in the posttest only design. But for the multi-sample pretest-posttest design has received little attention regarding multiple comparison tests. The Bryant-Paulson MCP has been suggested for analysis of covariance for last three decades, but no study has been found that examined this procedure’s Type I error rate and statistical power. Dayton has recently proposed a new approach to multiple pairwise comparisons that has a greater true-model rate than several traditional MCPs in context of posttest only design. In the present study the statistical power and Type I error rate of five traditional MCPs and the true model rate of six selected MCPs are compared for completely randomized multi-sample pretest-posttest design. Five traditional MCPs examined are: the Shaffer (SFP), Hochberg (HBP), Bryant-Paulson (BPP), modified Hayter (MHP), and Bonferroni (BNP) procedures. Along with these five traditional MCPs, a new MCP is also considered in the present study: the Dayton model-testing procedure (MTP). Data were generated and manipulated under four data conditions: number of population compared, populations mean patterns, correlation between the covariate and dependent variable, and sample sizes. A total of 198 combinations of number of groups (3, 4, and 5), pattern of sample size per group and per correlation among covariate and dependent variable (.3, .5, and .8), and population mean configurations were manipulated using the computer simulated data. Based on the results of this study, the following conclusions were drawn: 1) the MHP and BNP maintained familywise error rate under the nominal alpha. For most of the conditions, the SFP, HBP, and BNP maintained familywise error rate two standard error below the nominal level; 2) with regards to any-pair, per-pair, and all-pairs power, the MHP outperformed the SFP, HBP, BPP, and BNP. The BPP was the second best procedure in terms of any-pair power. Regarding the per-pair and all-pairs power, the SFP was the second best procedure for J = 3 and 4 and HBP was the second best when J = 5; 3) the MTP consistently had the best true-model rate compared to the traditional MCPs; 4) for additional analyses when sample size of 20 and 25 per group were selected, the values of statistical power and true-model rate were increased for each MCP compared to the initial analyses when the original sample sizes were considered. The conclusion regarding the performance of MCPs did not change with the increased sample sizes.

▼ In the classical theory of statistical inference, data is assumed to be generated from a known model, and the properties of the parameters in the model are of interest. In applications, however, it is often the case that the model that generates the data is unknown, and as a consequence a model is often chosen based on the data. In my dissertation research, we study how to achieve valid inference when the model or hypotheses are data-driven. We study three scenarios, which are summarized in the three chapters. In the first chapter, we study the common practice to perform data-driven variable selection and derive statistical inference from the resulting model. We find such inference enjoys none of the guarantees that classical statistical theory provides for tests and confidence intervals when the model has been chosen a priori. We propose to produce valid "post-selection inference" by reducing the problem to one of simultaneous inference. Simultaneity is required for all linear functions that arise as coefficient estimates in all submodels. By purchasing "simultaneity insurance" for all possible submodels, the resulting post-selection inference is rendered universally valid under all possible model selection procedures. This inference is therefore generally conservative for particular selection procedures, but it is always more precise than full Scheffé protection. Importantly it does not depend on the truth of the selected submodel, and hence it produces valid inference even in wrong models. We describe the structure of the simultaneous inference problem and give some asymptotic results. In the second chapter of this thesis, we propose a different approach to achieve valid post-selection inference which corresponds to the treatment of the design matrix predictors as random. Our methodology is based on two techniques, namely split samples and the bootstrap. Split-sample methodology generally involves dividing the observations randomly into two parts: one part for exploratory model building, a.k.a. the training set or planning sample, and the other part for confirmatory statistical inference, a.k.a. holdout set or analysis sample. We use a training sample only to seek a subset of predictors, and then perform the estimation and inference on the holdout set. As far as inference after selection in linear models is concerned, the main advantage of this technique is, roughly speaking, that it separates the data for exploratory analysis from the data for confirmatory analysis, thereby removing the contaminating effect of selection on inference. We show that the our procedure achieves valid inference asymptotically for any selection rule. The third part of the thesis is an application of the split samples method to an observational study on the effect of obstetric unit closures in Philadelphia. The splitting was successful twice over: (i) it successfully identified an interesting and moderately insensitive conclusion, (ii) by comparison of the planning and analysis samples, it is clearly seen to have avoided an exaggerated…

▼ This study investigated the effectiveness of various analytical methods used for estimating R² shrinkage in multiple regression analysis. Two categories of analytical formulae were identified: estimators of the population squared multiple correlation coefficient (ρ²), and estimators of the population cross-validity coefficient (ρ_c²). To avoid possible confounding factors that might be associated with a real data set such as data nonnormality, lack of precise population parameters, different degrees of multicollinearity among the predictor variables, and so forth, the Monte Carlo method was used to simulate multivariate normal sample data, with prespecified population parameters such as the squared multiple correlation coefficient (ρ²), number of predictors, different sample sizes, known degree of multicollinearity, and controlled data normality conditions. Five hundred replicates were simulated within each cell of the sampling conditions. Various analytical formulae were applied to the simulated data in each sampling condition, and the "adjusted" coefficients were obtained and then compared to their corresponding population parameters (ρ² and ρ_c²). Analysis of the results indicates that the currently most widely used (in both SAS and SPSS) "Wherry" formula is probably not the most effective analytical formula in estimating ρ². Instead, the Pratt formula appeared to outperform other analytical formulae across most of these sampling conditions. Among the analytical formulae designed to estimate ρ_c², the Browne formula appeared to be the most effective and stable in minimizing statistical bias across different sampling conditions. The study also concludes that it is the n/p (sample size/number of predictor variables) ratio that affects the performances of these analytical formulae the most; different degrees of multicollinearity among predictor variables do not have dramatic influence on the performances of these analytical formulae. Further replicants on both real and simulated data re still needed to investigate the effectiveness of these analytical formulae. Advisors/Committee Members: Xitao Fan, ;.

▼ 1) Proteomic Data Pre-processing: Quantification and Normalization of Luminex Assay System High through-put genomic and proteomic technologies allow rapid analysis of molecular targets of thousands of genes at a time, either at the DNA, RNA or protein level. In these type of experiments variations in expression measurements can occur from a variety of sources. Our goal was to examine measurement and normalization techniques to reduce the experimental variation in data derived from a bead-based multiplex Luminex assay system which allows simultaneous measurements of proteins. Normalization for the Luminex assay system requires a fundamentally different approach than the case of traditional microarrays. In the Luminex assay system, each experimental unit is a plate and each plate has results for multiple subjects and analytes. We quantified performance among different measurement systems (fluorescent intensity, background in fluorescent intensity, and observed concentration) in both high and standard scanning systems. Various normalization techniques (scale normalization, quantile normalization, lowess curve normalization) were adapted to the Luminex data scenario and their performance was compared in two datasets. We used the coefficient of variation across plates to compare the performance of normalization methods. Median and Lowess normalizations appeared to result in reducing plate- to-plate variation the most. Quantile normalization does not appear to work well for these datasets. Our results suggest that simple normalizations such as scale and lowess curve normalizations perform better than complex methods such as quantile normalization. Complex methods may add noise and bias to the normalized adjustment when the assumptions are not met. 2) Integration of microRNA and mRNA by Weighted Gene Co-expression Network AnalysisWe focus on the step-by-step network construction and module detection of mRNAs by weighted gene co-expression network analysis (WGCNA), followed by identifying the strong correlation between miRNA and module eigengenes. We then evaluate whether the predicted mRNA targets are differentially present between a given module and other modules by using the Fisher's exact test. We retained miRNAs who are significant in the fisher exact test, and are strongly correlated with eigengenes in a module.Next we relate modules to disease status by using eigengene network methodology, we found that 11 out of 13 modules are significantly related with disease status. Enrichment analyses by DAVID software are implemented for the 11 modules. We also run step-by-step network construction and module detection of miRNAs and found 6 modules. We used LASSO regression to explore the relationship between miRNA and mRNAs. The predictors are module eigengene of miRNA and the outcome is the eigengene from each mRNA module. We found that 1 miRNA "hsa_miR_25" is significantly anti-correlated with mRNA Magenta module. "hsa_miR_25" belongs to the miRNA module "blue" that is also predictive to Magenta mRNA module…

Objectives This review assesses the effects of oral therapies compared to placebo and interferon beta-1a in adults with relapsing-remitting multiple sclerosis (RRMS). Search methods We searched the MEDLINE, EMBASE, Cochrane Library, Web of Science (January 1980 to April 2011) and clinincaltrials.gov (April 2011) databases and reference lists of articles. The FDA website was also searched. Selection criteria Double-blind, placebo-controlled, randomized trials of RRMS patients who were treated with fingolimod, cladribine, laquinimod or interferon beta-1a. Data collection and analysis Two reviewers independently assessed articles for inclusion. Data extraction and quality assessment was completed by one reviewer and verified for accuracy. Meta-analysis and indirect treatment comparison methods were used to estimate relative measures of efficacy. Results Although 11 trials involving 7,127 participants were included in this review, only 2,109 (30%) and 1,738 (24%) participants contributed to the direct and indirect estimates respectively, for the primary outcome, annualized relapse rate. Oral therapy and interferon beta-1a had a significantly different rate of relapse compared to placebo (Mean difference [MD] -0.21, 95% conﬁdence interval [CI] -0.27 to -0.16 , p < 0.00001 and MD -0.33 95% CI -0.65 to -0.01). There was a significant risk reduction of 37% and 19% in the number of patients with at least one relapse for oral therapy and interferon beta-1a compared to placebo respectively. Safety analysis favoured placebo for both sets of trials (p=0.002 and p=0.04). Indirect estimates were not significant for all three outcomes however; comparability between direct evidence was noted. Conclusions Oral pharmacotherapy and interferon beta-1a are effective compared to placebo in controlling relapse rate in patients with RRMS. The indirect measures of effect provide initial estimates of comparative efficacy and incorporation of future evidence will be necessary.

▼ R is simultaneously a programming language and an environment for statistical computation and graphics. We will be interested in understanding the functionality of the packages of R, creating a new one, capable to execute the Joint Regression Analysis, ACR, automatically. The JRA is a technique very used to interpret networks in the domain of the evaluation of cultivars. In this technique we find a group of procedures that allow us to do the comparison and selection of cultivars. In a first phase we resorted upon the zigzag algorithm in the adjustment of linear regressions, one for cultivar, where in the regressions the controlled variable is the environmental index that measures the productivity of the several environments. The values of the environmental indexes and of the coefficients of the regressions, will be adjusted simultaneously by the referred algorithm, that according to Oliveira, A. (2007) is based on a iterative process where the minimizations alternate between the regression coefficients and the environmental indexes. In order to evaluate the quality of the adjustment obtained by the algorithm we will calculate the determination coefficient R2 using a linear model for the residues. Contrarily to what is usual in this case we are interested in obtaining low values of R2, because a close value to zero indicates a good adjustment, while larger value indicate that the zigzag algorithm was not capable to extract all the relevant information from the data. Through the Upper Contour Method, we will exemplify, which cultivars integrate that Contour and later, observed through t test and the methods of multiple comparisons of Scheffé, Bonferroni and Tukey, which cultivars, at level of significance of 5%, are significantly dominant or dominated, in the determined intervals of dominance. In this work, after presenting the theoretical aspects, in Chapter 5 we will develop a set of functions and routines, creating a "package" in language R that will allow us, to analyze in Chapter 6, a set of simulated data for verification of the applicability of the same.

▼ With the advent of the personal computer, mechanistic nutrient uptake models have become widely used as research and teaching tools in plant and soil science. Three models NST 3.0, SSAND, and PCATS have evolved to represent the current state of the art. There are two major categories of mechanistic models, transient state models with numerical solutions and steady state models. NST 3.0 belongs to the former model type, while SSAND and PCATS belong to the latter. NST 3.0 has been used extensively in crop research but has not been used with woody species. Only a few studies using SSAND and PCATS are available. To better understand the similarities and differences of these three models, it would be useful to compare model predictions with experimental observations using multiple datasets from the literature to represent various situations for woody species. Therefore, the objectives of this study are to: (i) compare the predictions of uptake by the NST 3.0, SSAND, and PCATS models for a suite of nutrients against experimentally measured values, (ii) compare the behavior of the three models using a one dimensional sensitivity analysis; and (iii) compare and contrast the behavior of NST 3.0 and SSAND using a multiple dimensional sensitivity analysis approach. Predictions of nutrient uptake by the three models when run with a common data set were diverse, indicating a need for a reexamination of model structure. The failure of many of the predictions to match observations indicates the need for further studies which produce representative datasets so that the predictive accuracy of each model can be evaluated. Both types of sensitivity analyses suggest that the effect of soil moisture on simulation can be influential when nutrient concentration in the soil solution (CLi) is low. One dimensional sensitivity analysis also revealed that Imax negatively influenced the uptake estimates from the SSAND and PCATS models. Further analysis indicates that this counter intuitive response of Imax is probably related to low soil nutrient supply. The predictions of SSAND under low-nutrient-supply scenarios are generally lower than those of NST 3.0. We suspect that both of these results are artifacts of the steady state models and further studies to improve them, such as incorporating important rhizospheric effects, are needed if they are to be used successfully for the longer growth periods and lower soil nutrient supply situations more typical of woody species.

▼ When conducting analyses on high dimensional data, one could face statistical difficulties due to large dimensionality and the noisy nature of the data. In this dissertation, we specifically look into potential complexities one might encounter when analyzing electronic medical record (EMR) and functional magnetic resonance imaging (fMRI) data. Phenome-Wide Association study (PheWAS) is a newly proposed method that scans through phenotypes (Phecodes) with a specific genotype of interest using logistic regression. Since the clinical diagnoses in EMR are often inaccurate which can lead to biases in the odds ratio estimates, much effort has been put to accurately define the cases and controls to ensure an accurate analysis. Specifically in order to correctly classifying controls in the population, an exclusion criteria list for each Phecode was manually compiled to obtain unbiased estimates. However, this method could be inefficient and the accuracy of the lists cannot be guaranteed. We propose to estimate relative risk (RR) instead. With simulation and real data application, we show that RR is unbiased without compiling exclusion criteria lists. With RR as estimates, we are able to extend PheWAS to larger-scale phenotypes which preserve more disease-related clinical information than Phecodes. The main purpose of task-induced fMRI is to measure neuronal activities related to specific task. fMRI data usually require several preprocessing steps before analysis. Among all, spatial smoothing is a necessary step known to increase signal-to-noise ratios but the choice of degree of smoothing is often arbitrary. One critical statistical issue in fMRI analysis is the balance between Type I and II error rates. We first demonstrate the influence of the degree of smoothing and experimental factors on the trade-off between Type I and II error rates. Next, we propose to use second-generation p-values (SGPV) as an inference tool instead of the traditional p-values for hypothesis testing. By allowing the interval null hypothesis, we have shown that SGPV is able to alleviate the critical statistical issue by controlling Type I error rate more steadily while obtaining enough power. Advisors/Committee Members: Johnson, Robert (advisor), Kang, Hakmook (advisor).

▼ In the United States, voting is one of the most fundamental rights protected by the federal law. However, there is a growing concern over voter disenfranchisement and system inequity caused by long waiting lines. Studies have found that inappropriate voting resource allocation has deterred hundreds of thousands of U.S. citizens from voting. This research proposes an analytic framework to quantify the number of deterred voters and assess the resulting political consequences. We apply this framework to the 2012 Sandoval County General Election in New Mexico to study whether electoral outcomes were altered by “effective disenfranchisement” for a few closely contested offices. Furthermore, Indifference-Zone Generalized Binary Search (IZGBS) is developed to determine the minimum sets of resources needed to satisfy a given service level for elections with one or multiple bottleneck resources. What makes the problem challenging is the service level generally needs to be evaluated using discrete event simulations, which is slow and noisy. For example, there are no analytical methods to estimate the waiting time of the 99th percentile voter. Thus, simulation-based ranking and selection (R&S), also known as design and analysis of R&S experiments, are preferred than stochastic integer programming methods in this type of problems. The proposed approach incorporates constrained R&S with Generalized Binary Search (GBS) to provide computationally efficient and rigorous solutions. It also explores the intuitive monotone assumption that adding resources cannot harm average performance for relevant Discrete Event Simulation (DES) models, which has received little attention in the simulation literature previously.The method is based on the assumption of normal populations (but not requiring equal variances). Therefore, special attention is given to quantile-related outputs that are associated with asymptotically normal estimates. The asymptote is in the number of simulated voters on Election Day, which is often over one thousand. Later, IZGBS is applied to the Franklin County of Ohio and Sandoval County of New Mexico to establish the resource requirement so that voters can expect to wait less than thirty minutes. Several topics are suggested for future research, including building on IZGBS to provide optimization solutions for more general problems. Advisors/Committee Members: Allen, Theodore (Advisor).

▼ Sammanfattning Titel: Organisationsidentitet och ranking. En kvalitativ studie om hur uppfattningen av kommuners organisationsidentitet förändras av ranking. Nivå: Examensarbete på Grundnivå (kandidatexamen) i ämnet företagsekonomi Författare: Alexandra Eriksson och Annica Bylund Handledare: Niklas Bomark Datum: 2021 - Januari Syfte: Studiens syfte är att öka förståelsen för hur uppfattningen om organisationens identitet förändras när organisationen utsätts för flera rankningar och hur det förändrar uppfattningen av den sociala identiteten. Metod: Studien har sin utgångspunkt i den hermeneutiska vetenskapstraditionen och tillämpar en kvalitativ forskningsstrategi. Insamling av studiens empiriska data har skett genom totalt sex semistrukturerade intervjuer med medlemmar inom sex olika kommuner. Vår empiriska data tolkades och analyserades tematiskt för att se likheter och skillnader mellan data och den teoretiska referensramen. Resultat och slutsats: Vår studie ökar förståelsen för hur kommuner hanterar att utsättas för olika rankningar där det framkommer att de inte längre lägger lika stor vikt vid dessa. Istället ser de mer till SKR:s Öppna jämförelser som de anser är mer vetenskapligt baserade. Kommuner lägger inte heller någon vikt vid skillnader mellan olika rankingar eftersom dem har flera verksamhetsområden som utsätts för rankingar som mäter olika aspekter av organisationen. Uppfattningen om organisationsidentiteten och den sociala identiteten förändras inte på en styrelsenivå inom kommunen av rankingar. Detta eftersom de besitter tillräckligt med information om organisationens egenskaper och kan därför bestrida resultaten från rankingarna. Det är mer troligt att uppfattningen förändras längre ut i verksamheten där medlemmarna inte har samma helhetsbild. Studiens bidrag: Studien bidrar med en kombination av tidigare forskning om ranking, organisationsidentitet och social identitet. Den lyfter även fram kommunernas syn på ranking som tidigare inte representerats av forskningen. Studien belyser även hur kommuner kan hantera ranking för att motverka negativa förändringar av uppfattningen om organisationens identitet och därmed den sociala identiteten. Förslag till fortsatt forskning: Baserat på studiens resultat är det första förslaget att utföra en studie där flera nivåer inom kommunen reflekteras. Det kan ge en djupare förståelse för hur uppfattningen om organisationens identitet och den sociala identiteten förändras av rankningar och visa om det skiljer sig åt mellan medlemmar på en styrelsenivå och de längre ut i verksamheten. Det andra förslaget är att jämföra kommuner med andra organisationer för att undersöka om det är generellt förekommande att rankning inte längre orsakar reaktivitet eller förändringar i uppfattningen om organisationens identitet eller social identitet. För att göra denna form av studie djupare föreslår vi även att studien inkluderar företag både inom och utanför Sverige för att se om förekomsten av reaktivitet och förändrad…

▼ This dissertation pursues to find an answer empirically to the question of the revenue ranking between the multiple price auction and the single price auction. I also attempt to get empirical clues in terms of the efficiency ranking between the two. Under the assumptions of symmetric bidders and private independent value (PIV), I derive the optimal bidding conditions for both auction formats. Following the structural model estimation approach, I estimate the underlying distribution of market clearing price using the nonparametric resampling strategy and recover the biddersÂ unknown true valuations corresponding to each observed bid point. With these estimated valuations of the bidders, I calculate what the upper bound of the revenue would have been under the Vickery auction to perform the counterfactual revenue comparison with the actual revenue. I find that, ex-post, the multiple price auction yields more revenue to the Korean Treasury than the alternative. I also investigate the efficiency ranking by comparing the number of bids switched and the amount of surplus change which would occur when the bidders are assumed to report their true valuations as their bids. I find that the multiple price auction is also superior to the alternative in efficiency which supports the current theoretical prediction. Finally, I investigate the robustness of my model and empirical results by relaxing the previous assumptions. I, first, extend the model and estimation to the case of asymmetric bidders where the bidders are divided into two groups based on their size. It shows that the model and estimation framework are still valid and that the empirical findings are very similar to the symmetric case. I also test for the presence of common value (CV) component in the biddersÂ valuation function. I propose the simple regression model adopting the idea of the policy experimental approach. I obtain quite an inconclusive result in general but find some evidence supporting PIV for relatively higher bid prices while supporting CV for lower bid prices.

▼ In this dissertation, several essays in the field of bio-security are presented. The estimation of the probability of an FMD outbreak by type and location of premises is important for decision making. In Essay I, we estimate and predict the probability/risk of an FMD outbreak spreading to the various premises in the study area. We first used a Poisson regression model with adjustment dispersion associated with random simulation results from the AusSpead model to estimate the parameters of the model. Our estimation and prediction show that large cattle loss could be concentrated in three counties-Deaf Smith, Parmer, and Castro. These results are based on approximately 70% of the feedlots with over 10,000 cattle located in the three counties previously mentioned. In Essay II, our objective is to determine the best mitigation strategies in minimizing animal loss based on AusSpead simulation model. We tested 15 mitigation strategies by using multiple comparison. The results show that the best mitigation strategies for all four scenarios are regular surveillance, slaughter of the infected animals, and early detection. We then used the Mixed Integer Programming to estimate costs of disposing of animal carcasses and transportation. Results show that the unit disposal cost will vary with carcass scale and the unit transportation cost also varies with the distribution of the infected premises and disposal locations. FMD seems to have varying impacts on equity markets. In Essay III, we studied returns at three different levels of the stock market. We determined results in a structural break, and then estimated the impact of the announcement of confirmed cases of FMD disease on the volatility of stock market returns by using a GARCH-Mean model. Our results show that the structure break occurs on the day with the largest number of confirmed cases for meat product firms rather than the day of the first confirmed case. We found that the conditional volatilities over the FMD period are higher than those over the sample period. The announcement of confirmed cases had the largest marginal impact on meat products. Investors may always consider maintaining a portfolio consisting of index funds or hedge funds. Advisors/Committee Members: McCarl, Bruce A.
