Abstract

This analysis considers the validity of the assumptions of the Gaussian perturbation model as applied to landmark data collected for morphometric analyses. The primary conclusion is that the assumption of homoscedasticity is unrealistic when applied to biological data sets. We also point out some important difficulties associated with alternate models.
