WebBenjamini-Hochberg (BH) adjustment In contrast to the strong control of FWER, Benjamini and Hochberg [1995] introduced a method for controlling FDR, which is herein termed BH adjustment ( 10 ). Let be the pre-specified upper bound of FDR (e.g., q =0.05), the first step is to compute index: WebSummary. When you perform a large number of statistical tests, some will have P values less than 0.05 purely by chance, even if all your null hypotheses are really true. The Bonferroni correction is one simple way to take this into account; adjusting the false discovery rate using the Benjamini-Hochberg procedure is a more powerful method.
