Error discovery rate testing
WebThe false discovery rate formula (Akey, n.d.) is: FDR = E (V/R R > 0) P (R > 0) Where: V = Number of Type I errors (i.e. false positives) R = Number of rejected hypotheses.

WebIn the Benjamini–Hochberg method, hypotheses are first ordered and then rejected or accepted based on their p -values. A p -value is a data point for each hypothesis describing the likelihood of an observation based on a probability distribution. The Benjamini–Hochberg method begins by ordering the m hypothesis by ascending p- … http://evolution.gs.washington.edu/gs560/2011/lecture9.pdf
Web"In statistics, family-wise error rate (FWER) is the probability of making one or more false discoveries, or type I errors, among all the hypotheses when performing multiple … Web4 The positive False Discovery Rate The positive false discovery rate (pFDR) is a bit of a wrinkle on the FDR. Here, you try to control the probability that the null hypothesis is true, given that the test rejected the null. This method works by rst xing the rejection region, then estimating , which is quite the opposite of how the FDR is handled.

Begin with the False Nondiscovery Proprotion (FNP): the proportion of missed discoveries among those tests for which the null is retained.
