Discrimination in the presence of covariables

In this paper we develop a unified approach to the theory of discriminant analysis in the presence of covariables by partitioning the D2-statistic. We demonstrate the equivalence of the methods of Rao (1949) and Cochran and Bliss (1948). A study is made of the null and non-null distributions of the...

Zusammenfassung:In this paper we develop a unified approach to the theory of discriminant analysis in the presence of covariables by partitioning the D2-statistic. We demonstrate the equivalence of the methods of Rao (1949) and Cochran and Bliss (1948). A study is made of the null and non-null distributions of the test statistic, which is a function of D2 , for various hypotheses concerning the equality of mean vectors.
