WebTwo other false discovery rate de nitions have been proposed in the literature, where the main di erence is in how the R= 0 event is handled. These quantities are called the positive false discovery rate (pFDR) and the marginal false discovery rate (mFDR), and they are de ned as follows (Storey 2003, Storey 2007): pFDR = E V R R>0 ; mFDR = E[V ... In statistics, the false discovery rate (FDR) is a method of conceptualizing the rate of type I errors in null hypothesis testing when conducting multiple comparisons. FDR-controlling procedures are designed to control the FDR, which is the expected proportion of "discoveries" (rejected null hypotheses) that are false (incorrect rejections of the null). Equivalently, the FDR is the expected ratio of the number of false positive classifications (false discoveries) to the total number of posi…
