Thank you Maarten. Best Regards, Lynn Lee -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Maarten Buis Sent: Monday, October 22, 2012 5:14 PM To: statalist@hsphsun2.harvard.edu Subject: Re: st: oligit interpretation You can define multiple dependent variables, and thus multiple marginal effects, for this model. You seem to have three categories for your dependent variable, so you can look at the probability of getting category 1, getting category 2, or getting category 3. So that is already three different outcomes you can look at. Moreover, you have the latent variable. Than you can look at the odds of ending up in category 2 versus 1 and the odds of ending up in category 3 versus 1 or 2. So your first step needs to be to define more precisely what it is exactly what you want to know. You'll probably will have to get access to (and read) a book like: <http://www.stata.com/bookstore/regression-models-categorical-dependent-vari ables/>. -- Maarten On Mon, Oct 22, 2012 at 10:09 AM, Lynn Lee <lynn09v@gmail.com> wrote: > Dear all, > > I am not sure how to interpret the marginal effect in ordered logit model. > > For example, in a ologit model, the coefficient of age is -0.03, > (z=-17.43), the two threshold parameters are "/cut1=-1.4 , > /cut2=0.95".
