betafunctions: Functions for Working with Two- And Four-Parameter Beta Probability Distributions

Package providing a number of functions for working with Two- and Four-parameter Beta distributions, including alternative parameterizations, calculation of moments, and fitting of Beta distributions to vectors of values. Also includes functions for estimating classification accuracy, diagnostic performance and consistency, using what is generally known as the "Livingston and Lewis approach" in the psychometric literature as the foundational method, which makes extensive use of the Beta distribution.
