Abstract
The multivariate permutation tests based on the nonparametric combination - NPC methodology (Pesarin and Salmaso, 2010) provides an effective hypothesis testing solution to many complex real problems which are quite common in case of multivariate response for many applied research areas such as biomedical and engineering research (Corain and Salmaso, 2013). Despite in the literature permutation tests are mostly derived by means of heuristic arguments, their natural theoretical background must be referred to the sufficiency and conditionally principles of inference. In this work we review and discuss the theoretical and practical relevance of NPC tests showing their effectiveness and easiness-in-use to address the ranking problem of several multivariate populations (Arboretti et al., 2014).
