Temperature Downscale in ArcMap

I am attempting to downscale a plethora of temperatures points over a high resolution DEM, and have hit several roadblocks. On further research, I have found a method in which to execute this task, but am stuck on how to execute within ArcMap. The weighted linear function I plan to use is as follows `y=Bx+C` Where y=predicted temperature, B and C are coefficients, and x is the DEM layer.

TempThere are also several complex weighted functions that determine the influence of the station on the regression model as the specific DEM cell gains altitude away from the station and proximity away from the coastline. I've also attached the thesis in which this mirrors, which goes more in depth on the equations in question.

Any help would be great, thank you! Eric

have you looked at the regression tools

Exploratory Regression—Help | ArcGIS for Desktop

Geographically Weighted Regression (GWR)—Help | ArcGIS for Desktop

Ordinary Least Squares (OLS)—Help | ArcGIS for Desktop

I might be useful to pull out any equations that you feel pertinent beyond the basic regession equation you have shown.
