%description
This is an implementation of the Generalized Discrimination Score (also
known as Two Alternatives Forced Choice Score, 2AFC) for various
representations of forecasts and verifying observations. The Generalized
Discrimination Score is a generic forecast verification framework which
can be applied to any of the following verification contexts: dichotomous,
polychotomous (ordinal and nominal), continuous, probabilistic, and
ensemble. A comprehensive description of the Generalized Discrimination
Score, including all equations used in this package, is provided by Mason
and Weigel (2009).
