It looks to me as if you are confused between the old -xi:- syntax and
the new factor variable syntax. -xi:- is not needed in a modern Stata.
-eststo- is part of the -esttab- package from SSC/SJ, as you are
asked to make clear. But I suspect the main problem here is confusion
over factor variables.
