双边随机前沿模型的STATA源程序怎么写？求助&悬赏!

请教各位：我现在用双边随机前沿模型，有了数据后用stata写命令呢？求知道的同学给予方便，论坛币之类的可以再商量！十万火急，求助求助！！！

I have difficulties to understand your question !

STATA has a built-in command to estimate SFA. This is essentially a regression analysis where the error term consists of a random error and an inefficiency term, and again can be estimated for both production and cost functions. The syntax of the frontier command is:  

frontier depvar [indepvars] [if] [in] [weight] [, options]

I have no ideas if these files can help you or not, you can have a look firstly and make a decison on the price by yourself. Thanks !
