Fisher t distribution
WebMar 24, 2024 · A statistical distribution published by William Gosset in 1908. His employer, Guinness Breweries, required him to publish under a pseudonym, so he chose "Student." Given N independent measurements x_i, let t=(x^_-mu)/(s/sqrt(N)), (1) where mu is the population mean, x^_ is the sample mean, and s is the estimator for population standard … WebGosset, Fisher, and the t Distribution JOAN FISHER BOX* Letters from W.S. Gosset to R.A. Fisher are used to describe Gosset's first contacts and growing friendship with Fisher, their collaboration over the tabulation of Student's t, and the wider applications of Gosset's work that were made possible by Fisher's extension
