question 16

Multiple Choice

Quarterly figures for e-commerce retail sales were obtained from the first quarter of 2009 through the fourth quarter of 2015. A regression model was estimated to describe the trend in e-commerce retail sales over time. Suppose that for the regression model estimated using the data described, the Durbin-Watson statistic was calculated as 1.727. Using α = 0.01 we can conclude that

• A) there is evidence of positive autocorrelation.
• B) there is evidence of negative autocorrelation.
• C) there is no evidence of positive or negative autocorrelation.
• D) since 1.727 is greater than upper critical value, there is evidence of an outlier.
• E) as dL < 1.727 < dU, the test is inconclusive.
