The distributions of p-values computed by t-test and RankProd test. We compared the parametric t-test and the non-parametric rank product approaches to test which of these p-value (computed from one-sided test) calculation is robust for identifying truly differentially expressed genes (p = q = 0.05; |Δ| = 0.5).
