WebFrom the table, we get α = 0.05 two-sided comparison d ( a -1, f) = 2.66, where a - 1 = 5 and f = df = 30. Using the Bonferroni approach, if we look at the t -distribution for g = 5 … where is the number of false discoveries and is the number of true discoveries. The false discovery rate ( FDR) is then simply: [1] where is the expected value of . The goal is to keep FDR below a given threshold q. To avoid division by zero, is defined to be 0 when . Formally, . 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 collection and analysis of a large number of distinct variables in several individuals … See more Adaptive and scalable Using a multiplicity procedure that controls the FDR criterion is adaptive and scalable. Meaning that … 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): 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 See more • Positive predictive value See more

The false discovery rate (FDR) is given by ( ) ( ) V V E E V S R = + and one wants to keep this value below a threshold α: The Simes procedure ensures that its expected value ( ) V E R is less than a given α (Benjamini and Hochberg 1995). WebLearn the meaning of False Discovery Rate in the context of A/B testing, a.k.a. online controlled experiments and conversion rate optimization. Detailed definition of False … WebDescription Returns the interest rate per period of an annuity. RATE is calculated by iteration and can have zero or more solutions. If the successive results of RATE do not converge to within 0.0000001 after 20 iterations, RATE returns the #NUM! error value.
