WebLinear discriminant analysis (LDA) is one of the most popularly used classification methods. With the rapid advance of information technology, network data are becoming increasingly available. A novel method called network linear discriminant analysis (NLDA) is proposed to deal with the classification problem for network data. cloudinary management console - media libraryWebLR accepts continuous as well as categorical predictor variables while DFA accepts only continuous (or dummy) and no categorical predictors.
