How to predict the value for a location using other predictor variables?

Hi all
I have a point shapefile that has 3 variables like precipitation, temperature, and the runoff. I am using precipitation and temperature as predictor variables and runoff as dependent variable. Using the spatial relation of these variables, I need to predict runoff for the points in a shapefile for any changes in temperature and precipitation as shown below.

Eg
ID PPT TEMP RUNOFF
1 110 25 40
2 100 18 34

ID PPT TEMP RUNOFF
1 150 24 ?
2 90 17 ?

I think this problem is different then interpolation because I am not interested in predicting for unknown locations as well as I have multiple variables to be taken care of. I am just wondering if I can perfom any test like this in ArcGIS? If so, which tool should I use? Any light on this area would be highly appreciated?

Thanks!
