What test should I run to do this?
First you have to decide what model to build and what algorithm to use to fit the model.
Tests are meaningless until you have fit the model, and the idea of testing requires an hypothesis to be clearly stated, which has not happened. (For example, you might want to test that the effect of Interest is zero or some other number ... but as I said, this has not been stated)
So how are you going to fit this model (what algorithm or what PROC)? What hypothesis are you going to test?
