Class "anam" Gaussian Anamorphosis

Description

This Class contains the anamorphosis which describes the way samples can be transformed from raw (Y) to gaussian (Z) scale, and vice-versa

Objects from the Class

Objects can be created by calls of the form new("anam", ...). The anamorphosis function enables the user to turn from raw to gaussian (and vice versa).
