Fig. 12From: Power analysis for RNA-Seq differential expression studiesPower plot for the Wald test with equal dispersion parameters for TCGA breast cancer data set. Power was calculated for the Wald test with the empirical distribution (solid line) or with a chi-square distribution with 1 degree of freedom (dotted line) at 3 different mean expression levels, 19 different sample sizes (range 3-100), and a fold change of 2 under the alternative hypothesis with α=0.001Back to article page
