Hi Billy,

Thank you for your prompt response.
I used the ado file written by (Kwak, D. W.), please look at this
link: [https://www.msu.edu/~kwakdo/ivqreg.pdf.]
I tried to used this in the quantile regression model:
ivqreg log_earn age age2 married educ_* (diseased=visit ) , quantil(.1)
In this model educ (is sveral dummy for educ1, educ2 and educ3), I
create this dummy because this command doesn't work with i.educ.
When I run the model after creating 4 _cons give me this message
(conformability error).
Actually the problem is that; I cannot include the several dummy for
educ or the other variables in the model, but if I just use one dummy
for educ ( e.g. educ1) its okey.
I hope I could explain the problem.

Thank you, HZ

The program I found had a date of 2010 in it, which might mean that the author is no longer developing that program.
