eQuIPS: eQTL Analysis Using Informed Partitioning of SNPs - A Fully Bayesian Approach.

abstract：:This paper describes a general genetic model which encompasses both autosomal and X-linked inheritance as submodels. It allows one to test for X-linked inheritance of a trait by comparing the likelihood of X-linked inheritance to the likelihood of the general genetic model. The general model is formulated as two loci,...
