If the value of the Durbin-Watson statistic,d,satisfies the inequality d_L≤d≤d_U,where d_L and d_U are the critical values for d,then the test for positive first-order autocorrelation is inconclusive.

Question

Quizplus · Accepted Answer

This is true because if the Durbin-Watson statistic falls within the range of critical values for d, then the test is inconclusive and it cannot be determined whether there is positive first-order autocorrelation or not.
