I am not not a prof. If you insist on using titles my title is drs. (which
is not the plural of dr., or a misspelling of ds., but doctorandus (he who
may become doctor)

No, but I haven't used panel data much, so it is very well possible that it
exists without me knowing about it.

If you want to loop in Stata you should not store those values in vectors,
but in locals and use -foreach- to loop.
