WebThe q -value reverses this process. Suppose we decide how many (or what fraction of) hypotheses we want to reject, and then estimate how many false discoveries we should expect to incur. In other words, the q -value reverses the conditional probability above: q-value(t) = p(H = 0 T ≥ t). Web5.7.3 Validation.

The False Discovery Rate (FDR) – an important statistical concept

WebOct 12, 2016 · In 1995, Benjamini and Hochberg introduced the concept of the False Discovery Rate (FDR) as a way to allow inference when many tests are being conducted. The FDR is the ratio of the number of false positive results to the number of total positive test results: a p-value of 0.05 implies that 5% of all tests will result in false positives.

"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… " - False discovery rate 日本語

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.
