Fisher-snedecor test

Webh = fishertest(x) returns a test decision for Fisher’s exact test of the null hypothesis that there are no nonrandom associations between the two categorical variables in x, against the alternative that there is a nonrandom association.The result h is 1 if the test rejects the null hypothesis at the 5% significance level, or 0 otherwise. WebFinally, choose F (Fisher-Snedecor) if your test statistic follows the F-distribution. This distribution has a pair of degrees of freedom. Let us see how those degrees of freedom …

WebThe F-ratio distribution was first formalized in the mid-1930s by American mathematician G. W. Snedecor as a tool to improve the analysis of variance as introduced by English statistician R. A. Fisher in the late 1910s. The F-ratio distribution is a staple in modern statistics, where it forms the basis for the so-called F-test.
