In statistics, the Holm–Bonferroni method, also called the Holm method or Bonferroni–Holm method, is used to counteract the problem of multiple comparisons. It is intended to control the family-wise error rate (FWER) and offers a simple test uniformly more powerful than the Bonferroni correction. It is named after Sture Holm, who codified the method, and Carlo Emilio Bonferroni. WebSuppose that instead of performing one statistical test, we perform three such tests; e.g. three tests with the null hypotheses: H 0: μ 1 = μ 2; H 0: μ 2 = μ 3; H 0: μ 1 = μ 3; Note that if you use a significance level of α = .05 for each of the three analyses then the overall significance level is .14 since 1 – (1 – α) 3 = 1 – (1 – .05) 3 = 0.142525 (see Example 6 … unfiltered dogpile web site
