Discriminant: Get concentration ellipse area...


A command to query the Discriminant object for the area of the concentration ellipse of one of its groups.
Settings

Number of sigmas

determines the data coverage.

Discriminant plane

When on, the selected X and Ydimension will refer to the eigenvectors of the discriminant space, and, consequently, the area of the projection of the hyper ellipsoid onto the space spanned by these eigenvectors will be calculated. When off, the selected X and Ydimension will refer to the original dimensions.
