gives you a dummy "used" which lets you discriminate btw the ones that were
used and those that were not...

Betreff: st: how to find out which groups were dropped in panel analysis

Dear stata list,

I am currently doing analysis on panel data (73 countries, 1980-2006). A
number of 'groups' (countries) are not used in xtgee analysis due to missing
data (i presume?). Is there any way to find out exactly which groups were
used (from those that were not) after the analysis has been conducted?
Currently stata just informs me that xtgee was conducted on 40 groups and I
do not know which groups/countries these were.
Thanks for your help
