Benjamini & Hochberg/Yekutieli Procedure for Controlling False Discovery Rate 1.0

Executes the Benjamini & Hochberg (1995) procedure for controlling the false discovery rate (FDR) of a family of hypothesis tests. FDR is the expected proportion of rejected hypotheses that are mistakenly rejected (i.e., the null hypothesis is actually true for those tests). FDR is generally a somewhat less conservative/more powerful method for correcting for multiple comparisons than procedures like Bonferroni correction that provide strong control of the family-wise error rate (i.e., the probability that one or more null hypotheses are mistakenly rejected). This function implements both versions of the Benjamini & Hochberg procedure: the one that assumes independent or positively dependent tests and the one that makes no assumptions about test dependency. The latter procedure (published by Benjamini & Yekutieli in 2001) is always appropriate but is much more conservative than the former. Both procedures are quite simple and require only the p-values of all tests in the familyBenjamini, Y. & Hochberg, Y.
