Nettet1.33.7.2.2 Linear discriminant analysis. LDA is a classical technique to predict groups of samples. This is a supervised technique and needs prior knowledge of groups. Therefore, LDA is well suited for nontargeted metabolic profiling data, which is usually grouped. LDA is very similar to PCA, except that this technique maximizes the ratio of ...
