Overview; Functions ... 日本 Japanese (日本語) 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… takopii no genzai อ่าน

Web5.7.3 Validation. False discovery rates (false positives) are a major problem in proteomics and can be caused by: (1) the statistical process used to identify significant protein signal differences, and (2) the algorithms used for identifying the structures of such proteins. For example, 2D gels from treatment and controls or from different ... 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).
