Gene set enrichment analysis using Wilcoxon rank tests


Gene set enrichment analysis (GSEA) is typically based on tests derived from the Kolmogorov-Smirnov, which is underpowered and a need for simpler methods has been identified. The wgsea package contains functions for conducting GSEA using a Wilcoxon test to test for differences in the distribution of p values between SNPs within the gene set under test and a control set of SNPs.
