WebThe false discovery rate (FDR) is a less conservative approach to multiple comparisons correction than the traditional methods described earlier. While the Bonferroni false positive rate of 0.05 means that 5% of all results will be truly negative, the FDR value of 0.05 means that 5% of “declared” positive results are truly negative. 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. In a more basic form, the formula is just saying that the FDR is the number of false positives in all of the rejected hypotheses. The information after the (“given ...
