In the present work some permutation tests for the problem of comparing two samples in the case of ordinal categorical variables are discussed, within the methodology of nonparametric combination of dependent permutation tests. In particular a new permutation test based on the combination of a finite number of sampling moments is shown. The results of a simulation study where the permutation solutions are compared with the Wilcoxon test with correction for ties are finally reported.

Abstract
In the present work some permutation tests for the problem of comparing two samples in the case of ordinal categorical variables are discussed, within the methodology of nonparametric combination of dependent permutation tests. In particular a new permutation test based on the combination of a finite number of sampling moments is shown. The results of a simulation study where the permutation solutions are compared with the Wilcoxon test with correction for ties are finally reported.File in questo prodotto:
