Regression regression on the wall, which pitching-runs saved measure explains the most variance of all?
Here’s a bit more on how the empirical fielding-independent pitcher metric—eFIP— compares with Baseball Reference’s and Fangraphs’s pitching-runs saved measures. I’ve previously shown that eFIP does a better job in out-of-sample predictions, which is an important feature of a valid estimator of pitcher latent skill—a measure of an inherent ability level. But here I’ll just […]
