EllKEPT                 Kernel embedding of probability test for
                        elliptical distribution
KEPTED                  Provides an implementation of a
                        kernel-embedding of probability test for
                        elliptical distribution. This is an asymptotic
                        test for elliptical distribution under general
                        alternatives, and the location and shape
                        parameters are assumed to be unknown. Some
                        side-products are posted, including the
                        transformation between rectangular and polar
                        coordinates and two product-type kernel
                        functions.
