Tecniche di ricampionamento e verifica multidimensionale delle ipotesi

Abstract

The paper deals with some multidimensional testing problems when the permutational principle applies. The proposed solutions are based on without replacement resampling techniques and nonparametrical combination of several dependent first order tests. In particular, a multidimensional extension of a permutational t-paired, a MANOVA with categorical and quantitative variables and a dominance test for ordered categorical variables are given. Moreover, problems implying some violations of the permutational principle, such as treatment of missing values and the multidimensional Behrens-Fisher, are also discussed.
