With reference to the Yang Chang skull group query:
I am a devotee of Analysis of Dispersion combined with Factorial Design of CR
Rao (1965).
The model is Y = XB
Y is a n by 3k+c matrix of n rows of k xyz coordinates plus c covariates such
as size and weight covariates.
X is a n by p design
I want to compare skull morphology using geometric morphometrics from several
species with different diets in a same genus. But I don't know much about how
to analyze these shape data. What statistical analysis can I do? I know that
principal component analysis can be done to visualize shape
