I am trying to estimate technical efficiency, for stochastic frontier
analysis, conditional on a set of z variables, for panel data.

For cross-section, I understand the command:
frontier y x1 x2, distr(tnormal) cm (z1 z2) 
will do the trick.  

However, for the command xtfrontier I am able to get the technical
efficiency estimates, but not sure how to condition those on a set of z
variables as is available with the frontier command.  Is there a code to
compute this in stata?

xtfrontier y x1 x2, tvd [want to condition te on a set of z variables].
 Please help.

Sen.
