False discovery rate : ウィキペディア英語版 | False discovery rate The False discovery rate (FDR) is one way of conceptualizing the rate of type I errors in null hypothesis testing when conducting multiple comparisons. FDR-controlling procedures are designed to control the expected proportion of rejected null hypotheses that were incorrect rejections ("false discoveries"). FDR-controlling procedures provide less stringent control of Type I errors compared to familywise error rate (FWER) controlling procedures (such as the Bonferroni correction), which control the probability of ''at least one'' Type I error. Thus, FDR-controlling procedures have greater power, at the cost of increased rates of Type I errors.〔Shaffer J.P. (1995) Multiple hypothesis testing, Annual Review of Psychology 46:561-584, (Annual Reviews )〕 ==History==
