WebThe simple Bonferroni correction rejects only null hypotheses with p-value less than , in order to ensure that the FWER, i.e., the risk of rejecting one or more true null hypotheses (i.e., of committing one or more type I errors) is at most . The cost of this protection against type I errors is an increased risk of failing to reject one or more ...

See more In statistics, family-wise error rate (FWER) is the probability of making one or more false discoveries, or type I errors when performing multiple hypotheses tests. See more Within the statistical framework, there are several definitions for the term "family": • Hochberg & Tamhane (1987) defined "family" as "any collection of inferences for which it is meaningful to take into account some combined measure of error". • According to Cox … See more FWER control exerts a more stringent control over false discovery compared to false discovery rate (FDR) procedures. FWER control limits … See more Tukey (1953) developed the concept of a familywise error rate as the probability of making a Type I error among a specified group, or "family," of tests. Ryan (1959) proposed the related concept of an experimentwise error rate, which is the probability of … See more Some classical solutions that ensure strong level $${\displaystyle \alpha }$$ FWER control, and some newer solutions exist.
