Discriminant analysis plays an important role in statistical pattern recognition. Then, we use Bayes rule to obtain the estimate: Discriminant analysis (DA) provided prediction abilities of 100% for sound, 79% for frostbite, 96% for ground, and 92% for fermented olives using cross-validation.

Linear 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 probabilities \(P(Y=k)\) are estimated by the fraction of training samples of class \(k\).
