Q-value p-value fdr
WebWhen plotting adjusted p-values, I can just set the cut-off to -log10 (0.05) (see picture 1). However when plotting the original p-values, I need to set a different cut-off. You can … WebNote: The Q-value is not the same as the “Q” you sometimes see in statistics. Q on its own (as opposed to a Q-value) refers to elements in a set that don’t have a particular …

In other words, the q-value of a feature, is the … WebFeb 6, 2024 · The q-value method is based on the false discovery rate (FDR), hence versions of the q-value method can be defined depending on which estimator of the proportion of true null hypotheses, p0, is plugged in the FDR estimator. We implement the q-value method based on two classical pi0 estimators, and furthermore, we propose and …
WebAn FDR adjusted p-value (or q-value) of 0.05 implies that 5% of significant tests will result in false positives. The latter will result in fewer false positives. q-values. Q-values are …
WebIt makes sense to use that FDR (t) as the q-value of p, since we will get more predictions and a lower FDR at the same time! So q (p) = min t; p
