Using StatasMargins Command to Estimate and Interpret Adjusted Predictions and Marginal Effects Richard Williams [email protected] Edu Briefly explain what adjusted predictions and marginal effects are, and how they can contribute to the interpretation of results Feb 05, 2018 The manual documentation for xtreg clarifies that for this command, vce(robust) is implemented as vce (cluster panelvar). (Note to StataCorp: this is not clear in the help file. ) So the fact that you got the same results with the second and third is not at all surprising.
command tells Stata everything it needs to know about the data sets sampling weights, clustering, and stratification. You only need to svyset your data once.

Miller. Abstract We consider statistical inference for regression when data are grouped into clusters, with vce(ols), the default, uses the standard variance estimator for ordinary leastsquares regression.
regress also allows the following: Vce cluster command stata manual and vce(hc3) specify an alternative bias correction for the robust variance calculation.
The manual does not say why. Using the user written command listcoef I can get the betas for my regression. The question now is, is this a computational problem Stata has and I can safely use the listcoef results or is this a statistical problem and I cannot use them or only under certain conditions. This manual contains most of the very useful stata commands. Explore.

The. bootstrap command has several additional options which are described with detailed examples in Statas user manual [R, and they can all be incorporated into vce() syntax as well. Most of the options provide for more complicated resampling schemes. Using the, vce (cluster [cluster variable command negates the need for independent observations, requiring only that from cluster to cluster the observations are independent.
Additionally, the Stata User's Guide [U has a subsection specifically on robust variance estimates and the logic behind them. When you are using the robust cluster variance estimator, its still important for the specification of the model to be reasonableso that the model has a reasonable interpretation and yields good predictionseven though the robust cluster variance estimator is robust to misspecification and withincluster correlation.
Statas cluster command has no builtin data transformations, but because Stata has full data management and statistical capabilities, you can use other Stata commands to transform your data before calling the cluster command.
