Question:
Recall that Figure14.26 (a) gives n = 16 weekly values of Pages Bookstore sales (y), Pages advertising expenditure (x1), and competitor’s advertising expenditure (x2). When we fit the model y = β0 + β1x1 + β2x2 + ϵ to the data, we find that the Durbin–Watson statistic is d = 1.63̅. Use the partial Durbin–Watson table on the page margin to test for positive autocorrelation by setting α equal to .05.
