1. Phillips, Taylor. Using Transitivity with Nearest Neighbor to Reduce Error in Sample-Based Pearson Correlation Coefficients.

Degree: MS, Computer Science, 2010, U of Denver

Pearson product-moment correlation coefficients are a well- practiced quantification of linear dependence seen across many fields. When calculating a sample-based correlation coefficient, the accuracy of the estimation is dependent on the quality and quantity of the sample. Like all statistical models, these correlation coefficients can suffer from overfitting, which results in the representation of random error instead of an underlying trend. In this paper, we discuss how Pearson's product-moment correlation coefficients can utilize information outside of the two items for which the correlation is being computed. By introducing a relationship with one or more additional items that meet specified criterion, our Transitive Pearson product-moment correlation coefficient can significantly reduce the error, up to over 50%, of sparse, sample-based estimations. Advisors/Committee Members: Chris Gauthier-Dickey, Ramki Thurimella.
