Do you have a citation for that statement? I cannot convince myself
that it should be true.
After looking at the CRAN Task View, I would suggest the OP look at
rlm(MASS) or lmrob(robustbase).

There are multiple routes to "robust" statistics, but the quick

this question is probably friedman.test
I don't think friedman.test is robust to variance heterogeneity. It is
only robust to
non-normality.

I seem to remember a CRAN Task View on the area of Robust Statistics.

Dear list members,
I am looking for an alternative function for a two-way ANOVA in
the case
of
variance heterogeneity. For one-way ANOVA, I found oneway.test(),
but I
didn't find anything alike for two-way ANOVA. Does anyone have a
suggestion?
Thank you!
