The data represent a variety of variables that may explain a pitcher's ERA (earned run average), or the mean number of earned runs (runs given up excluding those due to fielding errors) yielded by a pitcher over the course of nine innings pitched. The potential explanatory variables are strikeout to walk ratio (K/BB), (strikeouts per nine innings (K/9), pitchers per batter faced (P/PA), pitches per inning pitched (P/IP), percentage of games won when pitching (W%), ground balls allowed (GB), fly balls allowed (FB), ratio of ground balls to fly balls (G/F), runs scored by pitchers team or run support (RS), and walks and hits per inning pitched (WHIP). Use forward selection, backward elimination, or stepwise regression to build a model that can be used to predict the earned run average of a pitcher.
