wGARP
Returns the Wilcoxon test statistic of the best model subset output from GARP. When using discrete values, such as the number of models agreeing on predicted presence location, the Wilcoxon test statistic equates the AUC.

n |
a numeric value specifying the number of models in the best subset output from GARP |
x |
a raster object of the summated raster of the best models output from GARP |
points |
a spatial object of presence data to use for testing locations |
For discrete cutpoints (n
), represents the number of models that agree on a predicted presence location.
The raster object (x
) should be a raster representing the number of models that agree on a predicted presence location per pixel and that outtput by sumRasters
.
The shapefile points
should presence locations that were not used by DesktopGARP for model training and those output by splitData
.
Returns the Wilcoxon test statistic.
