WebIn statistics, Fisher's method, [1] [2] 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 overall hypothesis ( H0 ). Similar to the entropy or mutual information, the Fisher information also possesses a chain rule decomposition. In particular, if X and Y are jointly distributed random variables, it follows that: where and is the Fisher information of Y relative to calculated with respect to the conditional density of Y given a specific value X = x. As a special case, if the two random variables are independent, the information yielded by the t…
