Density of global p values for the multiple-comparisons procedure used by Bugawan et al. (2003) under the global null hypothesis for two independent tests (a) and three independent tests (b). In panel a, P0≡F0(P(1),P(2)), where P1 and P2 are independently uniform on (0,1) and F0 is the cumulative distribution function of the order statistics, as discussed in the text. In panel b, P0≡F0(P(1),P(2),P(3)), where P1, P2, and P3 are independently uniform on (0,1). Densities are estimated from 10,000 Monte Carlo replicates.
