Fisher criterion
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 ). WebFisher Linear Discriminant Analysis (FLDA) FDA is a kind of supervised dimensionality reduction technique. In the case of diagnosis, data obtained from several states of health are collected and categorized in classes.
