Re: Incorporating Prior Information into RAPM
Hi, just to understand better because I haven't attempted something like this before. I guess by RAPM you mean regularized adjuststed plus/minus. So you are trying to regress Y (predict) shot attempts per 60 minute (as a way of predicting game outcome?) from the "dummy" X variables you ha...
