bayescount: Bayesian analysis of count distributions using MCMC
A set of functions to allow analysis of count data (such
as faecal egg count data) using Bayesian MCMC methods. Data is
analysed using any of the (zero-inflated) gamma Poisson
(equivalent to a negative binomial), (zero-inflated) simple or
independant Poisson, (zero-inflated) lognormal Poisson or
(zero-inflated) Weibull Poisson models. Returns information on
the possible values for mean count, coefficient of variation
and zero inflation (true prevalence) present in the data. A
complete faecal egg count reduction test (FECRT) model is also
implemented, which returns inference on the true efficacy of
the drug from the pre and post treatment data provided, using
non-parametric bootstrapping as well as using Bayesian MCMC.
