%description
Provides functions for the Bayesian analysis of some simple commonly-used
models, without using Markov Chain Monte Carlo (MCMC) methods such as
Gibbs sampling.  The 'rust' package
<https://cran.r-project.org/package=rust> is used to simulate a random
sample from the required posterior distribution, using the generalized
ratio-of-uniforms method.  See Wakefield, Gelfand and Smith (1991)
<DOI:10.1007/BF01889987> for details. At the moment three conjugate
hierarchical models are available: beta-binomial, gamma-Poisson and a
1-way analysis of variance (ANOVA).
