Hi,
I've got two raster layers to do with a specific crop:
Yields
Suitability Index for growing
What I'd like to do is use the suitability layer, which covers the entire globe, to impute the potential (expected) yield in places where the crop is not grown. I would do this using the actual yields layer.
I can't use rasters as inputs for the OLS or GWR tool. I tried converting them to vector format, doing a spatial join, and then running a regression but it won't work as the datasets are simply too big when I convert them to polygons.
How would I run a regression on rasters, to impute the expected values of one based on another?
Thanks!
