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 Pillai-Bartlett 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	0.036	0.047	0.011
	90	0.148	0.157	0.009
	150	0.312	0.314	0.002
0.5	30	0.311	0.333	0.022
	90	0.951	0.933	0.018
	150	0.998	0.997	0.001
0.8	30	0.838	0.769	0.069
	90	1.000	1.000	0.000
	150	1.000	1.000	0.000
