At least two presence locations and two background locations are required to train the model.
Presence and background locations are excluded from the model if they are outside of the study area, contain null values in required fields, or contain NoData in any explanatory training raster. This error occurs if fewer than two presence and two background locations remain after excluding invalid locations.
Provide input datasets with at least two presence and two background locations.
Alternatively, change the option of the Study Area parameter or remove explanatory training rasters that have NoData values inside the study area.
