st: pooled data using frontier comand

Hi
I am working with a very short panel (T=2) trying to estimate a
technical efficiency model using the frontier command. First of all, I
haven't used xtfrontier because I've read that the estimator are
consistent when T tends to infinity. However, using frontier command
on a pooled data may be problematic due to correlation within "i", so
I would like to know some ways which could control for this
correlation.
Best regard,
Ramiro
