Table 2.

Power for each test for N = 40.

Test Algorithm K Power (%) Corrected power (%)
ANOVA FO 995 69.8 66.5
FOCE 968 71.2 69.3
Wald FO 974 61.5 7.7
FOCE 905 57.2 24.7
LRT FO 958 90.2 48.7
FOCE 947 78.7 71.0

K is the number of data sets on which the test could be performed.

The corrected power was obtained using the fifth percentile of the empirical distribution of the test statistic under H0 as the cut-off value for the test.
