Routine to calculate the Generalized Discrimination Score (aka Two-Alternatives Forced Choice Score 2AFC) for the situation of continuous observations and continuous forecasts
afc.cc(obsv, fcst)
obsv |
vector with real-valued observations |
fcst |
vector of same length as obsv with real-valued forecasts |
This routine applies Eq.22 of Mason and Weigel (2009) to calculate the 2AFC.
