Dear Austin,

first thanks for your answer. I also found some of these articles to
read that could be useful, and I will do that. of course. I also found
out an answer in an old stata faq about the same problem where a guy
was suggesting the procedure below. What do you think about it?

sysuse auto, clear

	program bootit
        	version 8.0

        	// Stage 1
        	regress price foreign weight length
       		predict double phat, xb

        	// Stage 2
        	qreg mpg foreign phat

	bootstrap "bootit" _b, reps(1000) dots

thank you
