Package: BvCh 0.1.0

BvCh: Bivariate Chen Distribution: Density, Survival, Hazard, Plots and Estimates

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.
