Spatial regression

[Voldemort]

I have a data of 4500 locations with each location corresponding to a bank branch. I have 13 predictor variables and a dependent variable. I want to use proc spatialreg to do the spatial regression on this data . I did 80-20 split and made a spatial weights matrix on the 80% data ....I was able to get the predictions for the training data but how to incorporate that on the test data ?

This does work for linear regression but my issue is specific to spatial regression...Is there any alternative that supports proc spatialreg

The problem is spatial models have another key component and that's spatial weights matrix...How to incorporate that in proc score
