New box score metric: Estimated Impact
Posted: Mon Sep 16, 2013 5:13 pm
Just wanted to share my box score metric, Estimated Impact. It is based on a regression of elements from the box score against long term RAPM. It is better at predicting future outcomes and, in my opinion, more reasonable than other box score metrics (even other SPM metrics). And obviously, it's much more stable and less biased than regression based plus minus metrics (like APM and RAPM). Plus I went all the way back to '52 with it, so it gives a nice historical perspective.
