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

Package providing a number of functions for working with the Two- and Four- parameter Beta distributions, including alternative parameterizations and calculation of moments. Includes functions for estimating classification accuracy, diagnostic performance and consistency, using what's known as the Livingston and Lewis approach in the educational-measurement literature as the base method. Livingston and Lewis (1995) . Hanson (1991) <>. Glas, Lijmer, Prins, Bonsel and Bossuyt (2003) .
