▼ High-throughput sequencing technologies have been widely used in biomedical research, especially in human genomic studies. RNA Sequencing (RNA-seq) applies high-throughput sequencing technologies to quantify gene expression, study alternatively spliced gene and discover novel isoform. Poisson distribution based methods have been popularly used to model RNA-seq data in practice. Differential expression analysis of RNA-seq data has been well studied. However, the correlation structure of RNA-seq data has not been extensively studied. The dissertation proposes a multivariate Poisson-lognormal model for the correlation structure of RNA-seq data. This approach enables us to estimate both positive and negative correlations for the count-type RNA-seq data. Three general scenarios have been discussed. In scenario 1, one exon with one isoform, we propose a bivariate Poisson-lognormal model. In scenario 2, multiple exons with one isoform, we propose a multivariate Poisson-lognormal model. Extending to multiple exons level, the number of pairwise correlations increases accordingly. To reduce the parameter space, the block compound symmetry correlation structure has been introduced. And in scenario 3, multiple exons with multiple isoforms, we propose a mixture of multivariate Poisson-lognormal models. Correlation coefficients are estimated by the method of moments. At multiple exons level, we apply the average weighting strategy to reduce the number of moment equations. Simulation studies have been conducted and demonstrate the advantage of our correlation coefficient moment estimator, comparing to Pearson correlation coefficient estimator and Spearman's rank correlation coefficient estimator. For application illustrations, we apply our methods to the RNA-seq data from The Cancer Genome Atlas (TCGA, breast cancer study). We estimate the correlation coefficient between gene TP53 and gene CDKN1A with normal subjects. The results show that TP53 and CDKN1A are slightly negative correlated.

▼ The objective of this dissertation is to study properties of improved estimators of the parameters of interest in two different multivariate regression models, analogous to the fixed-X and random-X scenarios of multiple regression and compare the performance of these estimators with the usual least square estimator. In general, we study restricted versions of the multivariate regression problem based upon constraining the relationship between Y and X in some way where they may be known or unknown to the researcher prior to statistical analysis. Chapter two contains a study of the properties of improved estimation strategies for the parameters of interest in a capital asset pricing model under a general linear constraint. Asymptotic results of the suggested estimators include derivation of asymptotic bias, asymptotic mean square error, and asymptotic distributional risk. The asymptotic results demonstrate the superiority of the suggested estimation technique. A simulation study is conducted to assess the performance of the suggested estimators for large samples. Both simulation study and data example corroborate with the theoretical result. In Chapter three, we consider a multivariate multiple regression model when X is a fixed matrix. Here, we propose shrinkage and preliminary test estimation strategies for the matrix of regression parameters in the presence of a natural linear constraint. We examine the relative performances of the suggested estimators under the candidate subspace based on a quadratic risk function and the results are shown. A simulation study is conducted to compare the performance of the suggested estimators and two data examples are also presented. Our analytical and numerical results show that the suggested estimators perform better than the unrestricted estimator under the candidate subspace. In Chapter four, we consider a multivariate reduced rank regression model when X is random and we propose preliminary test and shrinkage estimation strategies. We investigate the asymptotic properties of the shrinkage and pretest estimators under a quadratic loss function and compare the performance of the suggested estimators under the candidate subspace and beyond. The methods are applied on a real data set for illustrative purposes and a simulation study is also presented. Advisors/Committee Members: Ahmed, Syed Ejaz (Economics, Mathematics, and Statistics).

▼ Clustered (includes longitudinal) count data arise in many bio-statistical practices in which a number of repeated responses are observed over time from a number of individuals. One important problem that arises in practice is to test homogeneity within clusters (individuals) and between clusters (individuals). As data within clusters are observations of repeated responses, the count data may be correlated and/or over-dispersed. Jacqmin-Gadda and Commenges (1995) derive a score test statistic H_S by assuming a random intercept model within the framework of the generalized linear mixed model by obtaining exact variance of the likelihood score under the null hypothesis of homogeneity and a score test statistic H_T using the generalized estimating equation (GEE) approach (Liang and Zeger, 1986; Zeger and Liang, 1986). They further show that the two tests are identical when the covariance matrix assumed in the GEE approach is that of the random-effects model. In each of these cases they deal with (a) the situation in which the dispersion parameter φ is assumed to be known and (b) the situation in which the dispersion parameter φ is assumed to be unknown. The second situation, however, is more realistic as φ will be unknown in practice. For over-dispersed count data with unknown over-dispersion parameter we use the score test procedure of Rao (1947) and derive three tests by assuming a random intercept model within the framework of (i) the over-dispersed generalized linear model (ii) the negative binomial model, and (iii) the double extended quasi likelihood model (Lee and Nelder, 2001). All these three statistics are much simpler than the statistic obtained from the statistic H_S derived by Jacqmin-Gadda and Commenges (1995) under the framework of the over-dispersed generalized linear mixed effects model. The second statistic takes the over-dispersion more directly into the model and therefore is expected to do well when the model assumptions are satisfied and the other statistics are expected to be robust. Simulations show superior level property of the statistics derived under the negative binomial and double extended quasi-likelihood model assumptions. Further, two score tests have been developed to test for over-dispersion in the generalized linear mixed model. The four score tests of homogeneity and the two score tests for detecting over-dispersion are applied to two real life data examples. A plan for future study is given.

▼ It is common for many establishment surveys that a sample contains a fraction of observations that may seriously affect survey estimates. Influential observations may appear in the sample due to imperfections of the survey design that cannot fully account for the dynamic and heterogeneous nature of the population of businesses. An observation may become influential due to a relatively large survey weight, extreme value, or combination of the weight and value. We propose a Winsorized estimator with a choice of cutoff points that guarantees that the resulting mean squared error is lower than the variance of the original survey weighted estimator. This estimator is based on very un-restrictive modeling assumptions and can be safely used when the sample is sufficiently large. We consider a different approach when the sample is small. Estimation from small samples generally relies on strict model assumptions. Robustness here is understood as insensitivity of an estimator to model misspecification or to appearance of outliers. The proposed approach is a slight modification of the classical linear mixed model application to small area estimation. The underlying distribution of the random error term is a scale mixture of two normal distributions. This setup can describe outliers in individual observations. It is also suitable for a more general situation where units from two distinct populations are put together for estimation. The mixture group indicator is not observed. The probabilities of observations coming from a group with a smaller or larger variance are estimated from the data. These conditional probabilities can serve as the basis for a formal test on outlyingness at the area level. Simulations are carried out to compare several alternative estimators under different scenarios. Performance of the bootstrap method for prediction confidence intervals is investigated using simulations. We also compare the proposed method with alternative existing methods in a study using data from the Current Employment Statistics Survey conducted by the U.S. Bureau of Labor Statistics.

▼ High-dimensional data are becoming increasingly pervasive, and bring new problems and opportunities for data analysis. This thesis develops methods for both supervised and unsupervised learning of high-dimensional data. The first topic we focus on is unsupervised metric learning in the context of clustering. We propose the criterion blur ratio, minimizing which yields a transformation (distance metric) that gives well separated and predictable clusters. For minimization we propose an iterative procedure, Clustering Predictions of Cluster Membership (CPCM), which alternately predicts cluster memberships and clusters these predictions. With linear regression and k-means, this algorithm is guaranteed to converge to a fixed point. The resulting clusters are invariant to linear transformations of original features, and tend to eliminate noise features by driving their weights to zero. Building on CPCM, we propose a method to perform orthogonal clustering. This is the unsupervised analog of faceted classification, a flexible way of organizing information based on multiple independent labelings (facets). Our aim is to generating such facets automatically. With increasingly high-dimensional data, there is more reason and demand for automated faceting. We propose CPCM-orth to achieve this. The resulting clusters inherit properties of CPCM, namely invariance to linear transformations and tend to eliminate noise features by driving their weights to zero. We observe that orthogonal clustering provides a list of clusterings for the user to choose from. Also, orthogonalizing with respect to "extraneous" clusterings leads to improved performance for single labeling as compared to traditional clustering algorithms. The third algorithm we propose is a step-wise version of Lasso. Lasso can be solved efficiently using convex optimization and leads to sparse and shrunk coefficient vectors. On the flip side, Lasso is known to have problems in the correlated setting, and the prediction optimal parameter selection for regularization often leads to a model with large number of noise variables. We propose an algorithm called stepwise Lasso which uses the Lasso for variable selection in a stepwise fashion. A bonferroni threshold and Gram-Schmidt orthogonalization of the predicted vector at every step form the core of this algorithm. Numerical results demonstrate that stepwise Lasso produces models which are sparse yet competitive in their predictive ability.

Degree: 2009, University of Maryland, College Park

▼ Estimating proportions of units with a given characteristic for small areas using small area estimation (SAE) techniques is a common problem in survey research. The direct survey estimates, usually based on area-specific sample data, are very imprecise or even unavailable due to the small or zero sample sizes in the areas. In order to provide precise estimates, a variety of model-dependent techniques, using Bayesian and frequentist approaches, have been developed. Among those, empirical best prediction (EBP) and hierarchical Bayes (HB) methods relying on mixed models have been considered for estimating small area proportions. Mixed models can be broadly classified as area or unit level models in SAE. When an area level model is used to produce estimates of proportions for small areas, it is commonly assumed that the survey weighted proportion for each sampled small area has a normal distribution and that the sampling variance of this proportion is known. However, these assumptions are problematic when the small area sample size is small or when the true proportion is near 0 or 1. In addition, normality is commonly assumed for the random effects in area level and unit level mixed models. However, this assumption maybe violated for some cases. To address those issues, in this dissertation, we first explore some alternatives to the well-known Fay-Herriot area level model. The aim is to consider models that are appropriate for survey-weighted proportions and can capture different sources of uncertainty, including the uncertainty that arises from the estimation of the sampling variances of the design-based estimators. Then we develop an adaptive HB method for SAE using data from a simple stratified design. The main goal is to relax the usual normality assumption for the random effects and instead determine the distribution of the random effects adaptively from the survey data. The Jiang-Lahiri type frequentist's alternative to the hierarchical Bayesian methods is also developed. Finally we propose a generalized linear mixed model that is suitable for binary data collected from a two-stage sampling design.

▼ Isotonic regression or monotonic regression (also called order restricted hypothesis testing) has been developed for a long time and it provides a simple, yet useful way to investigate the relationship between a general response variable and an ordinal predictor variable with an order constraint. The resulting model is usually a monotonic step function, which can be further simplified by combining those steps which do not differ greatly. Such an analog of isotonic regression is referred to as the reduced isotonic regression. The reduced isotonic regression model has the advantage of categorizing a continuous variable with less over-fitting and it can be viewed as a change-point model with unknown number of monotonic shifts. Only recently, isotonic regression has been applied in survival data analysis by Ancukiewicz, Finkel-stein and Schoenfeld (2003). However, reduced isotonic regression has not been studied in survival data analysis. In this dissertation, we explore the use of reduced isotonic regression in survival data analysis. Differently from the two step procedure, we integrate the second step (the 'reducing' step) into the first step through a dynamic programming (DP) algorithm. We term this approach 'flexible isotonic regression' because by pre-specifying the testing significance, we can have a full model or more parsimonious model, hence flexible. We start with the exponential distribution and then move on to the more general Weibull distribution. Finally, a piecewise proportional hazard (PPH) model with isotonic regression is described, which has a more non-parametric flavored estimate for the baseline hazard. Parameters are estimated with the maximum likelihood method. We apply this methodology to the Diabetes Control and Complication Trial (DCCT) data set. All three approaches, exponential, Weibull and PPH are used and the results compared. Models generated from the three approaches are very similar. All suggest a non-linear negative association between HbA1C and risk of severe hypoglycemia. With mild testing added, HbA1C values at 6.2, 7.3 and 9.6 are identified as potential change points in its association with severe hypoglycemia.

▼ In recent years the medical community has given increasing attention to the standardization and improvement of healthcare quality and safety. In particular, medical errors have been shown to be a significant source of preventable morbidity, mortality and healthcare costs. Observational data, including voluntary reporting databases of medical errors, have been suggested as an important tool in quality and safety research. For example, we consider MEDMARX, a large, national, voluntary reporting system for medication errors. This dataset provides large amounts of data from many healthcare facilities and can be useful for studying medication error. In this thesis, we summarize selected background literature and consider three issues in the application of statistical methods to the analysis of observational data in health services research. First, we develop Bayesian hierarchical models for quantifying the evidence in MEDMARX for the causal continuum hypothesis, which states that the causes and contributing factors of errors that result in patient harm are similar to the causes and contributing factors of errors that do not result in patient harm. We also use our models to identify the causes and contributing factors that may be aberrant from the causal continuum hypothesis. We found that the data strongly support the causal continuum hypothesis for most causes and contributing factors. Next, we develop a Bayesian hierarchical model to rank the combinations of error type and error causes that have the highest log odds of harm in MEDMARX. We compare this model to an empirical Bayes approach that was proposed for ordering medication-event combinations in an FDA spontaneous reporting database. In each approach, we consider the sensitivity of results to the specification of the random effects distributions. We found that both approaches provide reasonable orderings of the combinations of error characteristics, but the Bayesian hierarchical model with optimal Bayesian ranking provides a more accurate characterization of the evidence. Finally, we consider applications of propensity score methodology in adjusting for bias due to confounders when estimating the effect of a binary treatment. We compare stratification and regression approaches via Monte Carlo simulation, and illustrate the approaches in an analysis of the effect of insurance plan choice on satisfaction with asthma care in an observational study of asthma patients. In the simulations we considered, generalized additive models with a smooth term for propensity score outperform stratification, even when the regression assumption of additivity is violated.

▼ Tukey's traditional boxplot (Tukey, 1977) is a widely used Exploratory Data Analysis (EDA) tools often used for outlier detection with univariate data. In this dissertation, a modification of Tukey's boxplot is proposed in which the probability of at least one false alarm is controlled, as in Sim et al. 2005. The exact expression for that probability is derived and is used to find the fence constants, for observations from any specified location-scale distribution. The proposed procedure is compared with that of Sim et al., 2005 in a simulation study. Outlier detection and control charting are closely related. Using the preceding procedure, one- and two-sided boxplot-based Phase I control charts for individual observations are proposed for data from an exponential distribution, while controlling the overall false alarm rate. The proposed charts are compared with the charts by Jones and Champ, 2002, in a simulation study. Sometimes, the practitioner is unable or unwilling to make an assumption about the form of the underlying distribution but is confident that the distribution is skewed. In that case, it is well documented that the application of Tukey's boxplot for outlier detection results in increased number of false alarms. To this end, in this dissertation, a modification of the so-called adjusted boxplot for skewed distributions by Hubert and Vandervieren, 2008, is proposed. The proposed procedure is compared to the adjusted boxplot and Tukey's procedure in a simulation study. In practice, the data are often multivariate. The concept of a (statistical) depth (or equivalently outlyingness) function provides a natural, nonparametric, "center-outward" ordering of a multivariate data point with respect to data cloud. The deeper a point, the less outlying it is. It is then natural to use some outlyingness functions as outlier identifiers. A simulation study is performed to compare the outlier detection capabilities of selected outlyingness functions available in the literature for multivariate skewed data. Recommendations are provided.

▼ Fiducial inference was proposed by R.A. Fisher in 1930 to overcome what he perceived as a deficiency in Bayesian methodology – assuming a prior distribution without prior knowledge. Due to some controversy, fiducial inference quickly fell into disfavor by the statistical community and was left undeveloped by Fisher. There were several attempts over the subsequent decades to revive fiducial inference. Eventually a connection was drawn between fiducial inference and generalized inference, called generalized fiducial inference (GFI). Under the GFI paradigm, inference is performed by considering the generalized fiducial distribution on the parameter space with a flexibility similar to a posterior distribution in the Bayesian framework. GFI can be thought of as a transference of probability from the model space to the parameter space, and a generalized fiducial distribution is defined for the unknown parameters of the model. In this dissertation, we apply the generalized fiducial framework to the normal linear mixed model setting and to logistic models with mixed effects. GFI is a computationally-based mode of inference, and we develop sequential Monte Carlo algorithms to obtain samples from the generalized fiducial distribution on the parameter space. In the normal linear mixed model setting, the proposed method is found to be competitive or better when evaluated based on frequentist criteria of empirical coverage and average length of confidence intervals. In the logistic setting with mixed effects setting, the simulation study reveals that the generalized fiducial approach tends to have correct empirical coverage, along with providing finite confidence intervals in cases where competing methods have disjoint, infinite, or non-calculable intervals. For the final part of this dissertation, we developed a methodology for classifying an unknown powder as a particular harmful substance ( Bacillus anthracis spores) or not. A wavelet transformation was incorporated to allow for possible thresholding or standardization, and then a linear model technique using the known elemental structure of the harmful substance was used for dimension reduction, and finally a support vector machine approach was employed for the final classification of the substance. The method was applied to real-data produced from a laser-induced breakdown spectroscopy device.
