A set of R functions for calculating sample size requirements using three different Bayesian criteria in the context of designing an experiment
to estimate the difference between two binomial proportions.
Functions for calculation of required sample sizes for the Average Length Criterion,
the Average Coverage Criterion and the Worst Outcome Criterion
in the context of binomial observations are provided.
In all cases, estimation of the difference between two binomial proportions is considered.
Functions for both the fully Bayesian and the mixed Bayesian/likelihood approaches are provided.
