Dear STATALIST,
I have an OLS regression of household's pollution on household's income and other characteristics (cross-sectional data). I want to find two sub-samples for which the coefficients of income are significantly different. How can I do this in STATA?
PS: Doing the regression with dummies for income brackets doesn't help because I want the income OLS coefficients to be different between groups not the income levels.
Thanks,
