Title: Searching for Predictive Relationship Among Genes Based on Gene Expression Microarray Data by Distributional Coefficient of Determination
Author(s): Li-yu D. Liu*+ and Tailen Hsing

Keywords: cDNA microarray ; gene expression ; conditional probability distribution function
Abstract:

cDNA microarray has been broadly applied in measuring the expression levels of thousands of genes simultaneously. We propose a new statistical method to measure associations between expressions of genes. The procedure can be used to identify the most predictive gene set for any given gene in the data. Such information is indispensable in building regulatory gene networks. The method is illustrated by considering a melanoma data set containing 50 genes.
