WebHolm-Bonferroni method is a step-down version of the classic Bonferroni correction, which helps to control the family-wise error rate by comparing each test statistic with a critical value.... WebSep 17, 2012 · As stated by Holm (1979) "Except in trivial non-interesting cases the sequentially rejective Bonferroni test has strictly larger probability of rejecting false hypotheses and thus it ought to replace the classical Bonferroni test at all instants where the latter usually is applied."
