Hello,
If you code the gender as dummy variable ( for males -1 and for females 1)
and use this variable as covariate then you can do a regression of shape on
this dummy and work with the residuals..

This is something you can do in the EVAN tool box. I.e. quantify a
vector of shape variation and then remove it from future analyses.

Dear All!
I hope you can help me!
The thing is that I would like to compare mandibles of five populations
of two different mammal species. The problem is I also have sexual
dimorphism both in shape and size and small samples. Therefore I was
thinking if I could somehow eliminate the part of variation that is the
effect of gender and in subsequent analysis of phylogeny use pooled sexes.
I know how to get the 'allometry-free' shape data and do the test for
common slopes. But what about sexual dimorphism? Is it possible?
Thank you in advance!
