I am running a logit regression, while because my dependent variable and my independent variable are affecting each other simultaneously , which is (as I understood ) the problem of endogeneity, I have to use instrumental variable, which I have to estimate by OLS.
would you please help me how can I do it in SAS?
My main regression is logit, and the regression for Instrumental variable is OLS.
for more explanation;my model is like following:
adoption_new_technology(dummy)= a1*(age)+a2*(education)+a3*(job)+ a4*(interest_buy_insurance)
here if some one is adopted to new technology, it will affect his decision on buying insurance. here we have indogeneity in " interest_buy_insurance "
