Nick and David: Ok, I did -update all- on my stata8. Now I get the same
results in both versions stata 8 and stata9, showing that my xtabond
has been updated in Stata8 (Nick, yes I understand your point that the
update was made by Stata to version 8). What ultimately answered my
question was the information under "xtabond" when I did -help whatsnew-
after my updating. This info explains the errors that existed in the
nonupdated xtabond version.
Thanks all,
tewodaj
---------------------------------------
You've missed David's point.
To see the latest -xtabond-, you just need to
-update- your Stata 8. Stata 9 added masses
of things, but nothing to -xtabond-.
