On the Optimality of Several Algorithms on Polynomial Regression of Empicial Bayes Poisson Model
The empirical Bayes estimator for the Poisson mixture model in [1], [2] has been an important problem studied for the past 70 years. In this thesis, we investigate extensions of this problem to estimating polynomial functions of the Poisson parameter rather than just the parameter itself. We …

Statistical Models for Gene and Transcripts Quantification and Identification Using RNA-Seq Technology
… count data. In this thesis, we propose three model frameworks to address three important questions in RNA-Seq study. First, we propose to use finite Poisson mixture models (PMI) to characterize base pair-level RNA-Seq data and further quantify gene expression levels. Finite Poisson mixture …

A Mixture-based Framework for Nonparametric Density Estimation
The primary goal of this thesis is to provide a mixture-based framework for nonparametric density estimation. This framework advocates the use of a mixture model with a nonparametric mixing distribution to approximate the distribution of the data. The implementation of a mixture-based nonparametric …

Latent Class Model in Transportation Study
… be interpreted as to establish the statistical models for the latent structure of data. Over the past several years, the interest in latent class models has continuously increased due to their great potential in solving practical problems. In this dissertation, I developed several latent class …
