Durbin Watson and Panel data

    Hi boards.

    I keep getting low DW stats for my panel data regressions. When I fix it using AR(1), Cochrane Orcutt, first differencing etc my coefficients become insignificant while DW approaches 2.

    Just wondering if I should really be worried about DW in panel data.

    Thanks

    Absolutely - autocorrelation can inflate standard errors, bias parameter estimates, and lead to erroneous inference. Did you try using alternative specifications? Autoregressive error models are one route, but using alternative lag combinations can soak up the serial correlation, and give you a little more information on the long-term effects.

    Moved to the 'researcher' forum, since the marginal return on an extra day in the Economics forum was likely very low at this stage
