-xtpmg- (SJ) is a user-written program written for Stata 9 and so may
not understand the factor variable syntax introduced in Stata 11. You
will need to create an indicator (dummy) variable beforehand.

-outreg2- (SSC) is also a user-written program. Sometimes it does not
understand recent additions to Stata syntax.

You are asked to indicate where user-written programs you refer to come from.

You should not type spaces between time series operators and the
variables to which they refer. Using such operators depends on a
previous -tsset- or -xtset-.

You may be using different versions of Stata on different machines.
