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. -- José David Gómez Químico Farmacéutico Universidad Nacional [[alternative HTML version deleted]]
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 (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.
