Discriminant: Draw sigma ellipses...


A command to draw for each group from the selected Discriminant an ellipse that covers part of the multivariate data.
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 projection of the hyper ellipsoid onto the space spanned by these eigenvectors will be drawn. When off, the selected X and Ydimension will refer to the original dimensions.

Xmin, Xmax, Ymin, Ymax

determine the limits of the drawing area.

Label size

determines the size of the labels at the centre of the ellipse. No labels will be drawn when a value less than or equal to zero is chosen.
