Ellen: Not sure why these differences would occur but note that with two
groups of 3 observations each there are only 6!/(3!3!) = 20 possible
permutations. Not sure where your 720 came from. Also, I would not expect
a permutation test for homogeneity of dispersions to be very useful with
such
Dear all,
As I want to switch for my multivariate data analyses from PRIMER/PERMANOVA
to R, I am comparing all tests I am doing in the former with those
performed in the latter program, to see whether results agree.
I performed a test for the homogeneity of multivariate dispersions in both
