Web5.4 False Discovery Rate (FDR). A different paradigm to \(p\)-value adjustments was originally proposed by the Israeli statisticians Yoav Benjamini and Yosef Hochberg (1995), with additional theory due to John Storey (2004).A criterion more liberal than \(FWER\), called False Discovery Rate (FDR) was developed, largely to deal with large-scale … WebThe value q depends not only on that one comparison, but on the number of comparisons in the family and the distribution of P values. • The q values Prism reports are FDR-adjusted p values, not FDR-corrected P values.

"WebNov 12, 2024 · What does it mean for a gene set to have a small nominal p value (p<0.025), but a high FDR value (FDR=1)? The nominal p value estimates the significance of the observed enrichment score for a single gene set.

WebA third approach is to apply the FDR correction which estimates the number of false positives for a given confidence level and adjusts the critical p-value accordingly.
