Modifications of the Bonferroni-Holm procedure for a multi-way ANOVA

We present step-wise test procedures based on the Bonferroni-Holm principle for multi-way ANOVA-type models. It is shown for two plausible modifications that the multiple level α is preserved. These theoretical results are supplemented by a simulation study, in a two-way ANOVA setting, to compare the multiple procedures with respect to their simultaneous power and the relative frequency of correctly rejected false hypotheses.
