Genomic DNA copy number alterations are key genetic events in the
initiation and progression of human cancers. Recent advance in the
technique of microarray comparative genomic hybridization (array CGH)
enables one to screen genome-wide for all possible regions with DNA copy
number alterations, such as chromosome gains and losses, or localized
amplifications and deletions. In this book, we introduce two statistical
methods addressing two different questions for the data analysis of
array CGH. The first method---Cluster Along Chromosomes--- is developed
for calling gains and losses in CGH arrays. The second method--- Boosted
PRIM (Patient Rule Induction Method)--- is developed to search for
oncogenic pathways using array-CGH data. The performance of the methods
are illustrated through both simulation studies and real applications.
