Those predictor variables provide the best discrimination between groups. Discriminant analysis finds a set of prediction equations based on sepal and petal measurements that classify additional irises into one of these three varieties. I π k is usually estimated simply by empirical frequencies of the training set ˆπ k samples in class k Total of samples I The class-conditional density of X in class G k is f kx.
The functions are generated from a sample of cases for which group membership is.
The model is composed of a discriminant function or for. 46 of the between group variance This is one of the statistics used to answer the question How well does the model work. Likewise there is a matrix of pooled within-group variances and covariances. I π k is usually estimated simply by empirical frequencies of the training set ˆπ k samples in class k Total of samples I The class-conditional density of X in class G k is f kx.
