Doing -xtreg y x,i(varname) re
- -test x-
- -xtreg y,i(varname) re
produces the same message as above when the last command is used.

I am using the 6 Oct 2004 versions.

Any suggestions would be appreciated.

xtreg invest, re

works fine. I suspect this is because xtreg is relying on -tsset- rather than the -i- argument. Try tsseting your data and see if it works then.

NB As long as you are not using any real time-series functionality, there is nothing wrong with creating a "time" variable from _n within each panel and using that in tsset, even if the data do not have a time dimension.
