MAC OSX vs Win XP: Different stats test results!
If mulrank does any sort of random number generation or non-exhaustive randomization, you should set the seed of the random number generator first: set.seed(1) mulrank(3,6,data03$x)

Hi all, I wondered whether anyone has some advice on a stats-related 'sanity check', as I ran a nonparametric multivariate test (mulrank function as decribed by R. Wilcox, 2005) on both systems, but got different results (please see below for the system-specific outputs)! The functions I used are attached as well. Any advice would be much appreciated! Thanks in advance for getting back to me! Best wishes, Mareen ------------------------------------ Mac:
