Given a sample of 50 observations and 4 explanatory variables, what can you say about autocorrelation if (a) d = 1.05? (b) d = 1.40 (c) d = 2.50? (d) d = 3.97? Assume a=5% G22. Suppose you have a sample of 40 observations and 3 explanatory variables and you wantto test for autocorrelation. What can you say about autocorrelation if you have thefollowing Durbin-Watson statistics? Assume a=5%. G1 a. d=1.30 b. d=1.00 c. d=2.25 d. d=1.95 B. Work out questions1.
