Use the data in Problem 15.17 to compute a regression model after recoding the data by the first-differences approach. Compute a Durbin-Watson statistic to determine whether significant autocorrelation is present in this first-differences model. Compare this model with the model determined in Problem 15.17, and compare the significance of the Durbin-Watson statistics for the two problems. Let a =.05.
