From: Quantitative shape analysis with weighted covariance estimates for increased statistical efficiency
Fly wing data (P-FL1): error eigenvalues estimated using the Monte-Carlo data (where mean shape, eigenvectors, and measurement covariances are identical to the model which generated the simulated data) against the expected ones (Test A); using 2 model components; there is only marginal evidence of estimation bias before correction;the two dashed lines show the ±2.8σ range.
