Stata Panel Data Exclusive
help whatsnew18 // Look for "Panel data" section The difference between a standard Stata user and an exclusive one is not just knowing xtreg —it is mastering high-dimensional FE, cross-sectional dependence, dynamic GMM, and non-linear multilevel models. It is understanding when to use reghdfe over xtreg , when to apply xtscc errors, and how to validate instruments in xtdpdgmm .
xtscc y x1 x2, fe lag(4) This command automatically handles spatial and temporal dependence. Most Stata users never touch this because it requires understanding of the lag structure. Exclusive users test the lag length via autocorrelation plots before applying it. Are you modeling GDP growth with past GDP as a predictor? Then OLS and even fixed effects are inconsistent. You need Arellano-Bond or Blundell-Bond estimators. stata panel data exclusive

melogit y x1 x2 || id: x1, covariance(unstructured) This allows the effect of x1 to vary across panel units—something fixed effects cannot do. Most Stata users never touch this because it
