WebApr 2, 2024 · The parameter $\pi_0$ describes the proportion of p-values (or tests) that comes from the null hypothesis. To calculated q-values, the algorithm first estimates $\pi_0$, then calculates the q-value. Note that if you set $\pi_0=1$, which means that you believe all the p-values come from the null distribution, then q-value is equal to FDR.

WebCritical values and values. Determination of critical values. Critical values for a test of hypothesis depend upon a test statistic, which is specific to the type of test, and the significance level, , which defines the sensitivity of the test.
