function variance = lorentz_variance ( )

%*****************************************************************************80
%
%% lorentz_variance() returns the variance of the Lorentz PDF.
%
%  Discussion:
%
%    The variance of the Lorentz PDF is not well defined.  This routine
%    is made available for completeness only, and simply returns
%    a "very large" number.
