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。1995年Benjamini和Hochberg首次提出了FDR的概念,并给出了在多重检验中对它的控制方法。然而，当时组学海量数据尚未大量出现,开始并 ... WebWrong Discovery Rate. Read the latest news stories about Mailman faculty, exploration, and events.

WebApr 12, 2024 · FDR is a statistics term that occurs when we do multiple comparisons between groups to test the hypothesis; even if there is no difference between groups, we still observe that some tests get statistics significant with p < 0.05 [ 1 ]. If the null hypothesis is true, FDR is a fraction of positive tests that are false positive and your ... Benjamini (2010) said that the false discovery rate, and the paper Benjamini and Hochberg (1995), had its origins in two papers concerned with multiple testing: ...

See more 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, … 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 … 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: $${\displaystyle \mathrm {PCER} =E\left[{\frac {V}{m}}\right]}$$. Testing individually … 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.
