Remarks and examples stata.com Linear dynamic panel-data models include plags of the dependent variable as covariates and contain unobserved panel-level effects, fixed or random. By construction, the unobserved panel-level effects are correlated with the lagged dependent variables, making standard estimators inconsistent.Using the Stata defaults, robust regression is about 95% as efficient as OLS (Hamilton, 1991). In short, the most influential points are dropped, and then cases with large absolute residuals are down-weighted. Description of the data.
