WebMar 13, 2016 · 12. Richard Dawkins has described Ronald Fisher as "the father of modern statistics and experimental design", a line which is quoted in Fisher's Wikipedia biography. And also Anders Hald called him "a genius who almost single-handedly created the foundations for modern statistical science" in his book A History of Mathematical Statistics. In statistics, Fisher's method, also known as Fisher's combined probability test, is a technique for data fusion or "meta-analysis" (analysis of analyses). It was developed by and named for Ronald Fisher. In its basic form, it is used to combine the results from several independence tests bearing upon the same … See more Fisher's method combines extreme value probabilities from each test, commonly known as "p-values", into one test statistic (X ) using the formula $${\displaystyle X_{2k}^{2}\sim -2\sum _{i=1}^{k}\log(p_{i}),}$$ where pi is the p … See more In cases where the tests are not independent, the null distribution of X is more complicated. A common strategy is to approximate the null distribution with a scaled χ -distribution random variable. Different approaches may be used depending on … See more A closely related approach to Fisher's method is Stouffer's Z, based on Z-scores rather than p-values, allowing incorporation of study weights. It is named for the sociologist See more Dependence among statistical tests is generally positive, which means that the p-value of X is too small (anti-conservative) if the dependency is not taken into account. Thus, if … See more Fisher's method is typically applied to a collection of independent test statistics, usually from separate studies having the same null … See more • Extensions of Fisher's method • An alternative source for Fisher's 1948 note: [1] See more

An F-statistic is the ratio of two variances and it was named after Sir Ronald Fisher. Variances measure the dispersal of the data points around the mean. Higher variances occur when the individual data points tend to fall further from the mean.

WebWhat are F-statistics and the F-test? F-tests are named after its test statistic, F, which was named in honor of Sir Ronald Fisher. The F-statistic is simply a ratio of two variances. Variances are a measure of dispersion, or how far the data are scattered from the mean. Larger values represent greater dispersion.
