Comparison of the multitest adjustments for homogeneity tests. Number of true and false discoveries obtained under the different multitest adjustment methods over a varying proportion (% Effect) of the alternative hypothesis contributing to the family of comparisons. The sample size of each homogeneity test was small (N = 20). The alternative hypothesis represents Weak or Strong deviations from the null one. The absolute number of detected true discoveries among 10,000 is shown on the left side, while the absolute number of false discoveries is presented on the right side. Values are averages through 1,000 replicates.
