Note: ATET estimate adjusted for panel effects and time effects. OTR 12 Use xtdidregressif panel data. Use didregressif repeated cross-sectional data (i.e. surveys over time) Not significant at 5%, event did not have a significant effect on GDPpc.Stata’s gmm makes generalized method of moments estimation as simple as nonlinear least-squares estimation and nonlinear seemingly unrelated regression. Just specify your residual equations by using substitutable expressions, list your instruments, select a weight matrix, and obtain your results. Here we fit a Poisson model of the …In a pooled dataset with heteroskedasticity you should use robust standard errors. This will adjust the standard errors to take account of the heteroskedasticity. If you have a panel dataset then you are probably better off using clustered standard errors as your heteroskedasticity will be related to the reporting of each unit (firms).

Autocorrelation. Iterated GLS with autocorrelation does not produce the maximum likehood estimates, so we cannot use the likelihood-ratio test procedure, as with heteroskedasticity. However, Wooldridge (2002, 282–283) derives a simple test for autocorrelation in panel-data models. Drukker (2003) provides simulation results …The Stata Journal (2005) 5, Number 2, pp. 202–207 Estimation and testing of fixed-effect panel-data systems J.
