Refer to the Political Analysis (Vol. 17, 2009) study on predicting presidential elections, Exercise 14.44. Recall that a regression model with five independent variables was fit to data collected for n = 24 election years in order to predict Yt = percentage of the two-party vote won by the incumbent party's candidate in election year t. The Durbin-Watson d-statistic for the model was reported as d = 1.77. Is there evidence (at α = .05) of positively correlated errors in the model? Explain.
