WebFirst, note that the "q-value" has gathered two distinct meanings along time. The first being: the minimal FDR level for which hypothesis i is rejected (1). The second being: the … The q-value can be interpreted as the false discovery rate (FDR): the proportion of false positives among all positive results. Given a set of test statistics and their associated q-values, rejecting the null hypothesis for all tests whose q-value is less than or equal to some threshold $${\displaystyle \alpha }$$ … See more In statistical hypothesis testing, specifically multiple hypothesis testing, the q-value in the Storey-Tibshirani procedure provides a means to control the positive false discovery rate (pFDR). Just as the p-value gives the expected See more In statistics, testing multiple hypotheses simultaneously using methods appropriate for testing single hypotheses tends to yield many false positives: the so-called multiple comparisons problem.
