Performs flexible discriminant analysis and stores the results in predefined tables. It
involves the use of multivariate adaptive regression splines for obtaining a basis
transformation of the independent variables and performing the multivariate
non-parametric regression step in the Flexible Discriminant Analysis procedure.
