Abstract.
For example, when testing for equality of two distributions in a
two-sample problem where the treatment is presumed to act on more than  
one
aspect, .g. first and second moment, several different tests, each
specific to one of the aspects of interenst, are applied thus leading  
to a
multi-aspect testing issue. If the global testing is of interest, a
combination of several dependent partial tests becomes an issue.
This kind of problem is solved within the nonparametric combination  
(NPC)
of dependent permutation tests.
Several application examples are also presented. One of these, based on
the property that if two or more tests are unbisaed and at least one of
them is consistent their NPC is consistent, concerns the consistencty  
and
robustness of any permutation test. One more is concerning the exact
solution of the well-known Behrens-Fisher problem when data
exchangeability is assumed in the null hypothesis. A further one  
concerns
testing problems when the treatment effect is positive on some subjects
and negative on some others, as it occurs with drugs having genetic
interaction.
