Thanks for that. -xtset- was documented in Stata 9 as forthcomming, so
there would be no need to change to -levels- as -mkbalanced- won't work
in Stata 8 anyhow. the version statement of -mkbalanced- should
probably be:

version 9.2
version 9.1

I am not particularly interested in making this program more generally
available (e.g. through -ssc-), eventhough that is now trivially easy.
The reason is that I don't think that this command is very useful. This
way you can easily end up ignoring 90% or more of your data. All I
wanted to show is that if you want a command you can easily make one
