In biomod2: Ensemble Platform for Species Distribution Modeling

Description

calculate.stat is an internal biomod2 function to get scores, based on a misclassification table, of some referenced evaluation metrics.

Usage

  calculate.stat( Misc,
                  stat='TSS')

Arguments

Misc	a misclassification table
stat	either 'TSS', 'KAPPA', 'ACCURACY', 'BIAS', 'POD', 'FAR', 'POFD', 'SR', 'CSI', 'ETS', 'HK', 'HSS', 'OR' or 'ORSS'

Details
