This class contains simple descriptive statistics for Java
and contains only static methods. No instances of the class
are needed. This class will be expanded as I have the time
and interest.

This class throws all exceptions encountered. The number of
elements in the passed arrays of doubles must not exceed the
maximum value of int.

This class may be freely used without fees for any non-
commercial use. Commercial use requires my written
permission in advance. This class is Copyright 1997 by
