WebIn the Benjamini–Hochberg method, hypotheses are first ordered and then rejected or accepted based on their p -values. A p -value is a data point for each hypothesis describing the likelihood of an observation based on a probability distribution.

Here, you try to control the probability that the null hypothesis is true, given that the test rejected the null. This method works by rst xing the rejection region, then estimating , which is quite the opposite of how the FDR is handled.
