bang: Bayesian Analysis, No Gibbs

Description

Performs Bayesian analyses using some simple commonly-used models. The multivariate generalized ratio-of-uniforms method is used to simulate random samples from the required posterior distribution. The user can either choose hyperparameter values of a default prior distribution or specify their own prior distribution.

Details

Currently three conjugate hierarchical models are available: beta-binomial, gamma-Poisson and 1-way Analysis of Variance (ANOVA). The function hef produces random posterior samples from for the beta-binomial and gamma-Poisson models. The function hanova1 does this for the 1-way Analysis of Variance (ANOVA). The rust package is used to produce these samples.

See vignette("bang-a-vignette", package = "bang") for a brief introduction to the package and vignette("bang-b-hef-vignette", package = "bang") and vignette("bang-c-anova-vignette", package = "bang") for illustrations of the use of the hef and hanova1 functions.
