st: RE: xtivreg2 invalid variable name r(198); while using first or fe option

["Schaffer, Mark E" <M.E.Schaffer@hw.ac.uk>]

Daniel,

A few things...

- You haven't told us which version of -xtivreg2- you're using or (in
this email) which version of Stata.

- You haven't told us what the variable names are.  It's hard to comment
on what might be invalid about the variable names without this bit of
information! 

- What part of the suggestion at

http://www.stata.com/statalist/archive/2009-12/msg00654.html

is unclear?

Cheers,
Mark

NB: Personally ... I prefer citing archived messages from the Statalist
archive at stata.com instead of 3rd party archivers.
