LDA: Linear Discriminant Analysis - Towards Data Science
WebJun 26, 2015 · LDA is basically a specific case of Canonical correlation analysis, and therefore it is ambidirectional. It can be seen as MANOVA (with the class variable as the independent factor) or, when the class is dichotomous, as a linear regression of the class as the dependent variable. WebLinear discriminant analysis (LDA), normal discriminant analysis (NDA), or discriminant function analysis is a generalization of Fisher's linear discriminant, a method used in statistics and other fields, to find a linear combination of features that characterizes or separates two or more classes of objects or events. The resulting combination may be … florian bauer hista
