Hello!
I am trying to estimate treatment effect (endogenous switching regression) using multinomial selection equation with three treatment categories . I have in fact tried to browse regarding the IMR after mlogit. But I still have two confusions from the materials I read: 1) is it three or two IMR that I need to calculate 2) should I include all the IMR in each of the three outcome equation (one for each category), or I need to include only IMR of each categories in their respective outcome regime? When the selection equation is binary I normally have two IMR and I include for example IMR1 in regime 1 and IMR2 in regime 2. But somehow become peplexed when selection eqn becomes multinomial. THANK YOU for your help.
