Test the hypothesis that there was no autocorrelation versus the alternative of negative autocorrelation in errors

What will be an ideal response?


The appropriate null and alternative hypotheses are H0 : ρ = 0, H1 : ρ < 0.
d = 2.28, n = 25, K = 2.
The cutoff points for the distribution of the Durbin-Watson test statistic are dL = 1.21 and dU = 1.55 (for α = 0.05 ) and dL = 0.98 and dU = 1.30 (for α = 0.01 )
The decision rule is as follows:
Reject H0 if d > 4 - dL
Accept H0 if d < 4 - dU
Test is inconclusive if 4 - dU < d < 4 - dL
Since 2.28 < 4 - dU = 2.45 and 2.28 < 4 - dL = 2.79, we fail to reject H0 at both levels of significance. The Durbin-Watson test gives sufficient evidence to conclude that there is no autocorrelation in the errors of the regression models at both the 5% and 1% levels.
