Did you know?
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 … See more Technological motivations The modern widespread use of the FDR is believed to stem from, and be motivated by, the development in technologies that allowed the collection and analysis of a large number of … See more Based on definitions below we can define Q as the proportion of false discoveries among the discoveries (rejections of the null hypothesis): $${\displaystyle Q=V/R=V/(V+S)}$$. where $${\displaystyle V}$$ is the number of false discoveries … See more Adaptive and scalable Using a multiplicity procedure that controls the FDR criterion is adaptive and scalable. Meaning that controlling the FDR can be very permissive (if the data justify it), or conservative (acting close to control of FWER for sparse … See more • False Discovery Rate Analysis in R – Lists links with popular R packages • False Discovery Rate Analysis in Python – Python … See more The settings for many procedures is such that we have $${\displaystyle H_{1}\ldots H_{m}}$$ null hypotheses tested and $${\displaystyle P_{1}\ldots P_{m}}$$ their corresponding p-values. We list these p-values in ascending order and denote them by See more The discovery of the FDR was preceded and followed by many other types of error rates. These include: • PCER (per-comparison error rate) is defined as: See more • Positive predictive value See more WebFDR(false discovery rate),是统计学中常见的一个名词,翻译为伪发现率,其意义为是 错误拒绝(拒绝真的(原)假设)的个数占所有被拒绝的原假设个数的比例的期望值。 …

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.
