If the value of the Durbin-Watson test statistic,d,satisfies the inequality d 4 −d_L,we conclude that positive first-order autocorrelation exists.

Question

If the value of the Durbin-Watson test statistic,d,satisfies the inequality d > 4 −d_L,we conclude that positive first-order autocorrelation exists.

Quizplus · Accepted Answer

The Durbin-Watson test statistic ranges from 0 to 4, where a value around 2 suggests no autocorrelation, values significantly less than 2 suggest positive autocorrelation, and values significantly greater than 2 suggest negative autocorrelation. The condition described does not correctly determine positive first-order autocorrelation.
