First, some warnings. The answer I give below is against my better judgement. I hope someone with more knowledge of "the threshold model" whatever that may be (you don't tell us the command) will comment on whether what you are attempting is necessary (we see a lot of questions about balanced panel data where the answer is "balance is not necessary").

The xtbalance command (user written software from SSC) is over 10 years old and has not been updated to what I assume is a newer syntax of egen which uses rowmiss() instead of rmiss(). You can fix this by editing the xtbalance.ado file. In Stata's command window

doedit "`c(sysdir_plus)'/x/xtbalance.ado"

and in the do-file editor window, change rmiss to rowmiss on line 34. Save the do-file. Then in Stata's command window run

do "`c(sysdir_plus)'/x/xtbalance.ado"

to cause the ado file to be rerun, replacing the program with the corrected version.

This may solve your problem, or it may just take you a few lines further to another piece of outdated code.

I would be much happier if you could get better advice that what I am giving you.

I have confirmed that the rmiss() function continues to exist in egen, so (a) my half-hearted answer at post #2 was incorrect, and (b) there is apparently something wrong with the installation of Stata on your system, since egen apparently is unable to identify the functions defined for it.

At this point I suggest you reinstall xtbalance

ssc uninstall xtbalance
ssc install xtbalance

to restore your version of xtbalance to the original code.

But, looking back on your previous posts to Statalist, I see you have used an unlicensed copy of Stata. It seems likely to me that the copy you are now using, licensed or not licensed, was not installed correctly, or fully. The ado file for the egen function rowmiss() will be named _growmiss.ado and the which command confirms its existence on my setup

. which _growmiss.ado
/Applications/Stata/ado/base/_/_growmiss.ado
*! version 1.0.0  04oct2004

as well as rmiss()

. which _grmiss.ado
/Applications/Stata/ado/base/_/_grmiss.ado
*! version 3.0.0  04oct2004
