A package for Bayesian analysis of probability estimates using beta distributions with R
The purpose of this package for R is to provide functions for visualizing and estimating beta distributions, their parameters, and quantiles. Some examples of functionality include:
- Plot a beta distribution with optional interval shading and line indicating expected value.
- Determine the bounds of a credible interval containing a specified percent of the probability.
- Estimate the parameters of a beta distribution from quantiles.
- Calculate the expectation of a beta distribution from its parameters.
- Determine the expected width of a confidence interval based on sample size.
- ggplot2 special geoms for interval shading and line indicating expected value.
Early pre-release development phase: caveat emptor
Updates may break backward-compatibility for a while. Please let me know if something isn't working or is confusing. Suggestions and code contributions via pull requests welcome!
The easiest way to install BetaBayes is by using the devtools package.
