Dear all, Would anybody please confirm or correct my understanding about the interpretation of these coefficients? Any reference would be appreciated. Y = Pr(vehicle fail the inspection); coded 1 if fail and 0 if pass X = ln(income) Z = other control variables logit(Y) = a + b_1*X + b_i*Z Are all of these correct? b_1 = elasticity = increase income will decrease the odds of Y by b_1 e^b_1 = odds ratio (OR) = odds of Y increase by a factor of [e^b_1] for every unit of ln(income) (OR-1)*100 = percentage change in odds of Y per unit change of ln(income) Thank you Anupit * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
