CBSS
Consensus-Based Sample Size
Version 1.0, July 2019
Four sets of R functions for calculating sample size requirements to ensure posterior agreement from different priors using a variety of Bayesian criteria. Each package includes functions for designing an experiment to estimate, respectively: - a single binomial proportion
- the difference between two binomial proportions
- a single normal mean
- the difference between two normal means.
This package is an implementation of the methods presented in

|
| Install instructions |
For each of the four packages, follow the instructions written for SampleSizeBinomial.
For both BinomialProportion packages, follow each step listed in the instructions, as these packages include a .C program.
For the other two packages (NormalMean), skip the first two steps.
