Jose: You might want to check out the multiresponse permutation procedure
(MRPP) family of statistics as they can perform permutation tests of
common distributions among groups of multivariate response data or perform
tests of equality of multivariate means among groups (i.e., a permutation
version of MANOVA). Note the former hypothesis test is more general than
a test of multivariate means as it detects multiple forms of difference in
distributions (shifts in medians, dispersion, both). I don't know whether
any of this has been programmed in R. You can obtain a simple user
friendly implementation in the USGS Blossom software
(www.fort.usgs.gov/products/software/blossom/blossom.asp) or obtain the
raw Fortran programs from Paul Mielke's web site at Colorado State
University Statistics Department.

[R] non parametric MANOVA
Dear colleagues,
has anyone an idea how to carry out a nonparametric manova for comparing K
groups?
has anyone a good package of non-parametric stats?
Thank you for your help.
