Re: st: re: positivity

["Teresa Linz" <tlinz@uni-bonn.de>]

I am using the sureg command to estimate cost share 
equations and the total cost equations. So do I have to 
programme my own code to impose positivity or how can I 
apply this reparamerisation explained in Stata. I do not 
really understand how I can do that.
Thanks Teresa
