A Wilcoxon rank-sum test is near equivilent to the GSEA method for set activity enrichment (see the fantastic paper (Gene set enrichment analysis made simple)https://www.ncbi.nlm.nih.gov/pubmed/20048385])
If our parametric method is so sensitive, it should be able to outperform the Wilcoxen at least
