Gwas p value threshold
WebA p-value threshold (alpha) of 0.05 yields a FPR of 5% among all truly null features. A q-value threshold of 0.05 yields a FDR of 5% among all features called significant. The q-value is the expected proportion of false positives among all features as or more extreme than the observed one. In our study of 1000 genes, let’s say gene Y had a p ... Web× 100), with the constraint that p-value cutoff is ≤ 0.05. An FDR-like analysis is also performed where the expected (by chance) and observed SNVs at various p-value thresholds (10-5, 10-4, 10-3, 10-2, 0.05) are computed and visualized (Figure 3). The p-value cutoff is revised to the highest threshold that satisfies an expected/
