The Durbin-Watson statistic has a value of D = 0.01. -What conclusion about autocorrelation in the model can we draw using the value of the Durbin-Watson statistic and the critical limits, dL=1.87736 and dU=1.88270? A)  There is evidence of positive autocorrelation. B)  There is evidence of negative autocorrelation. C)  There is no evidence of positive autocorrelation. D)  There is no evidence of negative autocorrelation. E)  As D falls between the critical values, the test is inconclusive. The Durbin-Watson statistic has a value of D = 0.01.
