Robustness of asymptotic and bootstrap tests for multivariate homogeneity of covariance matrices Robustez de testes assintóticos e de Bootstrap para homogeneidade de covariâncias em populações multivariadas
The present work emphasizes the importance of testing hypothesis on homogeneity of covariance matrices from multivariate k populations. The violation of the assumption of the homogeneity of covariance matrices affects the performance of the tests and the coverage probability of the confidence region...
