Note: one does not "correct data" for the effects of phylogeny. What one
does is to estimate some parameter (such as correlation or regression)
taking into account the expected lack of independence due to phylogeny.
Note also that these parameter estimates are unbiased whether or not one
takes phylogeny into account. The main benefit is that one gets a better
estimate of their variance.

Dear morphometricians,
I am comparing allometric vectors among eight closely-related fish species.
However, I would like to correct the data to remove phylogenetic effects
(e.g. using standard comparative methods).
Has anyone already done a multivariate comparisons of allometries,
taking phylogeny into account?
If so, could you give me information about your methods?
Could you suggest me some relevant papers about this topic?
Many thanks in advance!
All the best,
Bruno
