Gwas p-value calculation
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 ...
