WebLinear Discriminant Analysis (LDA) tries to identify attributes that account for the most variance between classes. In particular, LDA, in constrast to PCA, is a supervised method, using known class labels. Script output: explained variance ratio (first two components): [ 0.92461621 0.05301557] Python source code: plot_pca_vs_lda.py.

One of the key assumptions of linear discriminant analysis is that each of the predictor variables have the same variance. An easy way to assure that this assumption is met is to scale each variable such that it has a mean of 0 and a standard deviation of 1. We can quickly do so in R by using the scale () function: # ... e consult knebworth surgery
