%description
Probability density, survival and hazard functions, random generation,
graphical displays and maximum likelihood estimation for bivariate Chen
type models. Three constructions are covered: the Bivariate Chen
distribution with a singular component on the diagonal, the Bivariate
Extended Chen distribution, and the Bivariate Inverse copula Chen
distribution obtained through an inverse copula with Chen marginals.
Univariate Chen density, distribution, quantile, survival, hazard and
random generation routines are obtained from the 'reliaR' package.
