From: Quantitative shape analysis with weighted covariance estimates for increased statistical efficiency
Mouse mandible data (MM1): error eigenvalues estimated using the Monte-Carlo data (where mean shape, eigenvectors, and measurement covariances are identical to the 6-component model which generated the simulated data) against the expected ones (Test A); for this number of parameters there is now evidence of a systematic underestimate of covariance (prior to correction); the two dashed lines show the ±2.8σ range.
