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 and closely related distributions (i.e., the Gamma-
Binomial-, and Beta-Binomial distributions). Includes d/p/q/r functions for
Four-Parameter Beta distributions and d/p/r- functions for Beta-Binomial
distributions. Includes moment-generating functions for Beta distributions,
Binomial distributions, Beta-Binomial distributions, and observed value
distributions.
Includes 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.
