Hi everyone
I have character data for species on a phylogeny, but simple
transformations like log-transformations or square-root transformations are
not proving to be sufficient to get the data to be normal. If this were a
non-phylogenetic test, I would resort to something like a Spearman
correlation, which is non-parametric.
But with phylogenetic generalized least squares, is there any method that
is nonparametric?
Thanks!
