Proposition and validation of multivariate tests of independence between two groups of variables

Autor: Vânia de Fátima Lemes de Miranda, Henrique José de Paula Alves, Daniel F. Ferreira

Publikováno v: Communications in Statistics - Simulation and Computation. :1-12

A commonly used test for the independence of two sets of variables from a normal multivariate population is the Wilks Lambda test or the multivariate likelihood ratio test (LRT). However, this test...

Proposition of new alternative tests adapted to the traditional T2 test

Autor: Henrique J. P. Alves, Daniel F. Ferreira

Publikováno v: Communications in Statistics - Simulation and Computation. 51:2287-2300

New alternative tests of the T2 Hotelling’s test for testing hypotheses on the mean vector of a normal p-variate population were proposed. These tests were based on comedian robust estimator of the...
