I am trying to estimate the producer specific
technical efficiency  (time invariant) using a
firmlevel panel data. When I use the "xtfrontier"
command as outlined in the help, stata is returning an
no observations
I haven't worked with the panels earlier. Can anyone
suggest what is the nature of problem here? I would
appreciate any help on this.
