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.
