Dear Statalist,
I would like to estimate Stochastic Frontier Models but my residuals are skewed in the wrong direction.
I have read on this paper http://www.ntu.edu.sg/home/guiying.wu/FHWFinal20121226.pdf that it is possiblet to impose right skeweness as a constraint.

Is anybody of you familiar with this procedure and can give me some details on how to perform it? 

Thank you very much,
Laura
