top Newey-West standard errors when Durbin-Watson test results are fine up vote 3 down vote favorite I am running a time-series regression. The Durbin-Watson statistics is very close to 2. In such a situation, would it still be better to use Newey-West standard errors, or is it ok to use OLS standard errors? regression standard-error autocorrelation robust-standard-error neweywest share|improve this question asked Apr 3 '15 at 19:26 financial theory 424 add a comment| 1 Answer newey west eviews 1 active oldest votes up vote 5 down vote accepted First, I would recommend to use a software package that not only reports the Durbin-Watson test statistics but also a p-value. That might give you more of an indication how close or far from 2 the statistic actually is. Furthermore, you may consider other tests for autocorrelation, e.g., Breusch-Godfrey etc. And if there is no evidence for autocorrelation (or heteroscedasticity) then the OLS standard errors are probably fine. A pragmatic approach could also be to simply try whether using Newey-West standard errors makes a relevant difference. If the autocorrelations in the residuals are small, then Newey-West should lead to very similar results anyway. share|improve this answer answered Apr 4 '15 at 18:13 Achim Zeileis 3,5951417 1 +1. Regarding the last paragraph: In small samples, as in below 50 or so observations, Newey West standard errors often give oversized tests though. –Student001 Apr 4 '15 at 19:49 2 Yes, good point. With all HC and HAC standard errors one should also keep in mind that they are less efficient if the standard assumptions do hold. –Achim Zeileis Apr 4 '15 at 21:46 Thanks very much. The sample size is above 100 observations. I've checked Newey-West standard errors and they are indeed not too far from HC standard errors. &nd
