Microarray is an important technology which enables people to
investigate the expression levels of thousands of genes at the same
time. A series of methods are proposed in this book to to detect
differentially expressed genes while controlling the false
discovery rate. In Chapter 1 and 2, a brief introduction of the
Affymetrix GeneChip microarray technology and a literature review
of the related works on this matter is provided.In Chapter 3, a
t-mixture model based method is proposed to detect differentially
expressed genes. In Chapter 4, a t-mixture model based false
discovery rate estimator is proposed to overcome several problems
of the current empirical false discovery rate estimators. In
Chapter 5, a two-step false discovery rate estimation procedure is
proposed to correct the overestimation of the false discovery rate
caused by differentially expressed genes. In Chapter 6, a novel
estimator is developed to estimate the proportion of equivalently
expressed genes, which is an important component of the false
discovery rate estimators.
