Effect of potential outliers. Consider the simpler model
Chapter , Problem 11.28(choose chapter or problem)
Effect of potential outliers. Consider the simpler model of Exercise 11.26 for this analysis. (a) Two movies have much larger U.S. revenues than predicted. Which are they and how much more revenue did they earn than predicted? (b) Remove these two movies and redo the multiple regression. Make a table giving the regression coefficients and their standard errors, t statistics, and P-values. (c) Compare these results with those from Exercise 11.26. How does the removal of these outlying movies impact the estimated model? (d) Obtain the residuals from this reduced data set and graphically examine their distribution. Do the residuals appear approximately Normal? Explain your answer.
