Elizabeth:
The cases used in your regression are marked by e(sample), 
so if you type -sum polrisklag gdpcapgr if e(sample) - you 
will get the summary statistics using the same sample as in 
your regression. You must do this after your regression, 
since it is the regression command that makes the e(sample).

Subject: st: Summary Statistics and Xtabond

I'm using the xtabond command and would like to have the summary statistics (mean std.dev max min) of the variables included in the estimations. The "estat summarize" command reports the summary statistics of the differenced variables  (please see output below). I have two questions:

(1) How do I obtain the summary statistics for the actual variables (e.g., polrisklag, gdpcapgr..)

(2) Is it possible to get the data for the sample used in the regressions? I'm using an unbalanced panel data and therefore countries with one observation are dropped. How do I get the list of countries included in the estimations?
