http://www.serjeonstats.com/2024/05/family-wise-error-vs-false-discovery.html#! WebFDR (false discovery rate) and FWE (family-wise error rate) are two ways to measure the number of errors made by a statistical method in a multiple testing problem. Suppose you have a number of hypotheses about some parameters of interest (say regression parameters), and the null hypotheses are , the alternative hypotheses are .

WebNov 1, 2009 · The false discovery rate (FDR) control procedure was used in order to correct for multiple comparisons (Benjamini and Hochberg, 1995; Lage-Castellanos et al., 2010; Groppe et al., 2011;Luck, 2014 ... http://rcompanion.org/rcompanion/f_01.html WebSep 5, 2024 · The False Discovery Rate (FDR) is definitely a weakening of FWER. In general F D R ≤ F W E R, so the FDR is more liberal (more rejections) than the FWER. A final word, I wouldn't go into saying that " Bonferroni is not a good method when comparisons are more that 3 or 4, as it is too conservative" as your search concluded. megan counts

WebApr 24, 2024 · In general, methods for family-wise error rate control are aimed at controlling the probability of any type I error occurring across a family of hypotheses, while methods for false discovery rate control are instead designed to control the proportion of positive results that are type I errors across a family of hypotheses. WebWe demonstrate that the false discovery rate approach can overcome these inconsistencies and illustrate its benefit through an application to two recent health …

WebSometimes people use a false discovery rate of 0.05, probably because of confusion about the difference between false discovery rate and probability of a false positive when the null is true; a false discovery rate of 0.05 is probably too low for many experiments.
