What it means to control the Type I error for a family
WebThe familywise error rate is the probability of making one or more Type I error in a family or set of comparisons. Boneferroni Inequality Define α as the per-comparison error rate … WebFeb 24, 2024 · For example, medical researchers can run statistical tests on tens of thousands of genes at once. Even with a false discovery rate of just 5%, this means hundreds of tests could result in false discoveries. One way to control the false discovery rate is to use something known as the Benjamini-Hochberg Procedure. The … pruning climbing roses in the fall
(PDF) Familywise Error in Multiple Comparisons
WebThe family-wise error rate (FWER) is the probability of rejecting at least one true , that is, of making at least one type I error. The Bonferroni correction rejects the null hypothesis for each , thereby controlling the FWER at . Proof of this control follows from Boole's inequality, as follows: WebThe standard practice for pairwise comparisons with correlated observations is to compare each pair of means using the method outlined in the section "Difference Between Two Means (Correlated Pairs)" with the addition of the Bonferroni correction described in the section " Specific Comparisons ."
