A Stochastic Frontier analysis under self selection

[Fissha Asmare]

Dear StataList,

I am trying to estimate the effect of Stochastic Frontier analysis under self-selection using panel data.

I want to combine the Method developed by Greene 2010 with a multinomial endogenous switching regression.

Is there any inbuilt STATA command or any other command to do this?

Any help is appreciated!

Thank you
