Are you sure you transferred all the line breaks from Austin`s original
-program-? If you can reproduce the error, -trace- it and show the lines
where Stata chokes...

Thanks Austin and Martin for the discussion. 

Austin's code did run for me few hours ago, however, I could not obtain the
same results when I ran it again. Any idea? I am using Stata Version 11.

Austin`s code does run for me, and does deliver the desired result. To
appreciate the difference, you have to make -esttab- display the standard
errors as - esttab re, scal(estat estatp j jp) se(%10.9fc)-. 

Note it is necessary to reload the -xtoverid2- command from Austin`s site,
as the latest version dated yesterday now returns r-class results that
should enable Kelvin to capture his desired results...

Thanks Austin for the codes, 

I tried to run the following codes, but I got an error message when I ran
the third last line -x2-. Please see the error message.
