More model informationFigure 27 of the book Virtual Outcrop Models of geological structures. Moment of inertia (Principal Component Analysis, PCA) planar regression of a point cloud with an ellipsoidal perfectly oblate distribution. The the maximum and intermediate eigenvalues are nearly identical, and much larger than the minimum eigenvalue. The best-fit plane, i.e., the plane perpendicular to K3 (the eigenvector associated to the minimum eigenvalue) is a useful descriptor of the point cloud.
