%description
Density, distribution function, quantile function, and random generation
for the generalized Beta and Beta prime distributions. The family of
generalized Beta distributions is conjugate for the Bayesian binomial
model, and the generalized Beta prime distribution is the posterior
distribution of the relative risk in the Bayesian 'two Poisson samples'
model when a Gamma prior is assigned to the Poisson rate of the reference
group and a Beta prime prior is assigned to the relative risk. References:
