Description: Package providing a number of functions for working with Two- and 
    Four-parameter Beta and closely related distributions (i.e., the Gamma-
    Binomial-, and Beta-Binomial distributions), including parameterization in
    terms of moments, and fitting of Beta distributions to vectors of values.
    Includes d/p/r- and a function and for calculating moments of Beta-Binomial
    distributions. 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 which models observed-score distributions in terms of the Beta-
    Binomial distribution. A shiny app is available, providing a GUI for the
    Livingston and Lewis approach when used for binary classifications. For
    url to the app, see documentation for the LL.CA() function.
