%description
The Cauchy distribution is a special case of the t distribution when the
degrees of freedom are equal to 1. The functions are related to the
multivariate Cauchy distribution and include simulation, computation of
the density, maximum likelihood estimation, contour plot of the bivariate
Cauchy distribution, and discriminant analysis. References include:

t distribution". Acta Applicandae Mathematicae, 102(1): 99--118.
