represents a p-dimensional ellipsoid centered at the point with semi-axis radii aligned with the coordinate axes.
represents a p-dimensional ellipsoid with semi-axis radii aligned with the direction .
- To use , you first need to load the Regression Common Functions Package. You can do this by using , which will automatically load the Regression Common Functions Package, or you can load the package directly by using .
- is used to represent ellipsoidal regions such as EllipsoidQuantile and EllipsoidQuartiles.
- Two-dimensional objects can be plotted using Graphics.
- If the direction matrix is a permutation of the identity matrix, the direction matrix is automatically dropped, reordering the radii if necessary.
