Testing whether genetic variation explains correlation of quantitative measures of gene expression, and application to genetic network analysis.

Abstract excerpt

Genetic networks for gene expression data are often built by graphical models, which in turn are built from pair-wise correlations of gene expression levels. A key feature of building graphical models is the evaluation of conditional independence of two traits, given other traits. When conditional independence can be assumed, the traits that are conditioned on are considered to 'explain' the correlation of a pair...
