The FDR is the ratio of the number of false positive results to the number of total positive test results: a p-value of 0.05 implies that 5% of all tests will result in false positives. An …
差异表达分析之FDR Public Library of Bioinformatics
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 … WebAs expected the number of p-values below 0.05 (or any other number) is 453, i.e. about 5% false positives as expected. Next I adjust the p-values using False Discovery Rate adjustment and estimate the q-values: q = p.adjust (p, method = "fdr") Now, if I understood correctly, selecting the hypothesis that have a q value of 0.05 one should get 5% ... black rose family
