If you mean: How can I ensure that I get positive estimates for
coefficients I expect to be positive, the answer is to reparametrise in
terms of logarithms. 

Otherwise, please expand on this question.

And I have another question; does anybody know how I could 
programme positivity for some coefficients in Stata?
