omissionGARP
Calculates the omission, or the true occurrence points that are not predicted as present, of the best models output from GARP.
1 | omissionGARP(n, x, points)
|
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 |
The discrete cutpoints (n
) represent 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 GARP for model training and those output by splitData
.
A list object containing:
Average.Omission
the average omission of the model subset
Total.Omission
the total omission of the model subset
