WebJan 10, 2024 · The qvalue package performs false discovery rate (FDR) estimation from a collection of p-values or from a collection of test-statistics with corresponding empirical null statistics. This package produces estimates of three key quantities: q-values, the proportion of true null hypotheses (denoted by pi_0), and local false discovery rates. WebFalse discovery rates, in contrast, are more of an exploratory tool. For example, suppose that we are testing 1000 hypotheses and decide beforehand to control FDR at level 5%. Whether this was an appropriate choice largely depends on the number of hypotheses that are rejected. If 100 hypotheses are rejected, then clearly this was a good choice. bounded lattice

In statistics, the false discovery rate (FDR) is a method of conceptualizing the rate of type I errors in null hypothesis testing when conducting multiple comparisons. FDR-controlling procedures are designed to control the FDR, which is the expected proportion of "discoveries" (rejected null hypotheses) that are false (incorrect rejections of the null). Equivalently, the FDR is the expected ratio of the number of false positive classifications (false discoveries) to the total number of posi…
