Fig. 1
Graphical illustration of the confident difference criterion method. The figure on the left panel and the right panel uses γ 0=0.5 and γ 0=0.7 separately. The μ g2−μ g1 measures the difference in the mean intensities of gene g between the two conditions. Both figures are drawn based on an assumption that the posterior mean of μ g2−μ g1 are positive. The shaded area in both figures measures the posterior probability for having a positive difference μ g2−μ g1
