WebFalse discovery rate control is a recommended alternative to Bonferroni-type adjustments in health studies Although still unfamiliar to many health researchers, the use of false discovery rate control in the context of multiple testing can provide a solid basis for drawing conclusions about statistical significance. WebGiven these error rates in just the usual % error format, it can be hard to know if (for example) a 0.2% rate for insufficient sample (ESR) is good or bad. On the Sigma scale, that transforms into a 4.4 Sigma, which is considered good.

The FDR is the expected proportion of rejections that are type I errors (false rejections). Anderson discusses this procedure here. This code is very easy to use.
