Not trying to be negative, but I do not think the model will work in the manner being approached b/c i get the feeling that variables are going to be difficult to attirubte a value and/or insignificant. However, if you try it, use an adjusted r squared. Best of luck.Yeah, I'd definitely share it if it works out and has a high R-squared and F-statistic (high predictive value).
I actually have done some equations for football capping. I encountered many issues so instead I switched to calculating the actual spread and finding value in (+/-) the points.
