Stochastic Frontier Analysis

[Mona Sameni]

I am trying to fit a translog production function with four inputs and I realize you need to do it through SFA for panel data.
Can someone post some clear example, how to do it step by step in stata.

I think Stata Manual has clear examples for SF models, take a look in http://www.stata.com/manuals13/xtxtfrontier.pdf

In addition, here is an interesting research using this technique

I have the same question. However, if we use a vector to be inputs (which means more than one variables are used in the model), how to write the command?
