Package providing a number of functions for working with Two- and Four-parameter Beta distributions, including parameterization in terms of moments, and fitting of Beta distributions to vectors of values. Also includes functions for estimating classification accuracy, diagnostic performance, and consistency, making use of 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. A shiny application is available, providing a GUI for the Livingston and Lewis approach. For link, see documentation for the LL.CA() function.
