Jeff Sagarin has been providing sports ratings for USA Today since 1985. In baseball his predicted RPG (runs per game) statistic takes into account the entire player's offensive statistics,

and is claimed to be the best measure of a player's true offensive value. The data above show the RPG and a variety of offensive statistics for a Major League Baseball (MLB) season for 20 members of the New York Yankees.

Let the dependent variable be the RPG statistic.

Find the best estimated multiple regression equation using backward elimination procedure.
