Figure 5From: Nonparametric tests for differential gene expression and interaction effects in multi-factorial microarray experimentsEmpirical power curves of three competing methods with respect to Shapiro-Wilk statistic. The empirical power curves of the three competing methods – MRT, FT and PFT, are plotted against the varying level of Shapiro-Wilk statistic. The Shapiro-Wilk statistic is employed to assess the magnitude of the heavy-tailedness in the distribution.Back to article page
