Re: [MORPHMET] Testing for sexual dimorphism

2015-04-29 Thread Carmelo Fruciano

Dear Alex,
I imagine most people would consider MAN(C)OVA and/or permutation  
tests for difference in multivariate means as the typical approach.  
Obviously, the choice of methods might also depend on the design and  
research question. There is a chance that with 10 observations per sex  
you might have limited statistical power when comparing within each  
species.

Best,
Carmelo

Dear morphometricians,
I have an interesting GMM dataset based on the cranial morphology of  
adult New World monkeys (platyrrhines) with a wide sampling of  
genera and species. I have approximately ten male and ten females  
for each species, and am interested in testing for size and shape  
dimorphism in each group. My current thinking is to use a Procrustes  
ANOVA to test for significant differences between males and females  
for each taxa, and wanted to enquire whether this was the standard  
approach with geometric morphometric data, or if an alternative  
approach would be more appropriate?

Any advice greatly appreciated,
Best wishes
Alex Bjarnason
