How does ArcGIS desktop estimate prediction values (out-of-sample) using a GWR calibration? Does it use the closest calibrated point? Does it use raster surfaces build with coefficients? Other Method?
Not sure if the answer is here (I'm not a statistician), but take a peek if you have not already:
Geographically Weighted Regression (GWR)—Help | ArcGIS for Desktop
Adding https://community.esri.com/community/gis/analysis/spatial-statistics for greater exposure.

Thanks for the information Chris. Unfortunately, there is nothing in the ArcGIS Help for GWR outlining the method to predict values for out-of-sample points which were not used in the initial calibration of GWR.
I will post any information any information I find.
