Question 6 [11 points] This question requires the use of gretl. The related file is baseball. gdt. You are not required to show script (although you can feel free to). But you are required to show the regression output that helped you to reach your conclusions. Researchers at Synergy Sports are conducting an analysis of a baseball player's offensive value. The dependent variable utilized in their analysis is the RPG (runs per game) statistic. Data collected from a recent MLB (Major League Baseball) season for 20 members of the NY Yankees is shown in the file baseball gdt The researchers have collected a variety of offensive statistics, the independent variables under consideration are: . H: hits TwoB: doubles ThreeB: triples HR: home runs . . RBI : runs batted in BB: bases on balls (walks) . . . SO: strikeouts SB: stolen bases CS: caught stealing . . . OBP: on-base percentage SLF: slugging percentage . AVG: batting average For the 12 predictor variables under consideration and with a=0.05 in tests: . Use the backward elimination procedure to develop the best estimated regression equation for predicting a player's RPG Which variables (if any) were eliminated? Write down the estimated regression equation
