Comparison of empirical and theoretical average power for the Benjamini and Hochberg (1995) procedure. Results are for three independent general linear multivariate models. Each hypothesis is tested with the Hotelling-Lawley trace. The sample size for each experiment is N ∈ {30, 90, 150}. The difference between treatment group means under the alternative is δ ∈ {0.2, 0.5 and 0.8}.

δ	N	Empirical Average Power	Theoretical Average Power	Absolute Difference
0.2	30	0.054	0.045	0.009
	90	0.158	0.156	0.002
	150	0.323	0.316	0.007
0.5	30	0.376	0.348	0.028
	90	0.954	0.953	0.001
	150	0.999	0.999	0.000
0.8	30	0.875	0.864	0.011
	90	1.000	1.000	0.000
	150	1.000	1.000	0.000
