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).
        Includes, among other things: - d/p/q/r functions for
        Four-Parameter Beta distributions and Generalized "Binomial"
        (continuous) distributions, and d/p/r- functions for Beta-
        Binomial distributions. - d/p/q/r functions for Two- and
        Four-Parameter Beta distributions parameterized in terms of
        their means and variances rather than their shape-parameters. -
        Moment generating functions for Binomial distributions,
        Beta-Binomial distributions, and observed value distributions.
        - Functions for estimating classification accuracy and
        consistency, making use of the Classical Test-Theory based
        'Livingston and Lewis' (L&L) and 'Hanson and Brennan'
        approaches. A shiny app is available, providing a GUI for the
        L&L approach when used for binary classifications. For url to
        the app, see documentation for the LL.CA() function. Livingston
