Dear morphometricians, I want to perform multivariate regression of landmark-specific signed asymmetries on the centroid size. The problem is I am dealing with the structure with object symmetry (namely, ventral side of a skull). Thus, dimensionality of an asymmetric shape variation is reduced and its covariance matrix is singular. I would greatly appreciate your advice how to modify standard multivariate regression procedure in this case.
