Webinflating the rate of false negatives unnecessarily. False Discovery Rate For large-scale multiple testing (for example, as is very common in genomics when using technologies such as DNA microarrays) one can instead control the false discovery rate (FDR), defined to be the expected proportion of false positives among all significant tests. Web1 Answer. Part of the reason you're confused may be that you are considering the special case that all null hypotheses are true (i.e. m = m0 ). When all null hypotheses are true, the FWER and FDR are indeed the same. For m independent tests of true null hypotheses, FDR = FWER = 1- (1-alpha)^ m. The difference comes when some null hypotheses are ...
