bayescount - Statistical Analyses and Power Calculations for Count Data and
Faecal Egg Count Reduction Tests (FECRT)
Power calculations and hypothesis testing for the
difference in mean of two negative binomial distributions A set
of functions to allow analysis of count data (such as faecal
egg count data) using Bayesian MCMC methods. 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 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. Functions to perform power analyses for faecal
egg counts (including FECRT) are also provided. A working
installation of JAGS (<http://mcmc-jags.sourceforge.net>) is
required for MCMC-based methods
