WebThe Fisher discriminant analysis method is one of the commonly used discriminant methods. The basic principle of the method is to construct a linear function yc consisting of p variables (the two variables selected in this study were SWC and VPD). WebJan 15, 2016 · In modern understanding, LDA is the canonical linear discriminant analysis. "Fisher's discriminant analysis" is, at least to my awareness, either LDA with 2 classes (where the single canonical discriminant is inevitably the same thing as the Fisher's classification functions) or, broadly, the computation of Fisher's classification functions in ...
