Such a search in Stata 9 should also bring up -xtmixed-, an oversight that we
will correct in a future ado update.
Since Geoff is presumably fitting a linear mixed model, -xtmixed- is the more
specialized solution. -xtmixed- does require Stata 9, so users of prior
versions can use -gllamm- instead.
