一种分类的新方法，与判别分析相似，但是能够直接寻找到多维方向，并且对数据同时分类(The Extended Canonical Variates Analysis (ECVA) is a new approach to classification. The aim is similar to discriminant analysis but it provides a direct solution to finding multivariate directions that separates groups and simultaneously classifying these.)
