My Apologies. I think i know what the problem is. Since I don't know how exactly your data and results look like, i thought i might create a different example. . webuse sysdsn4 qui mlogit insure age if male==1, base(1) estimates store m1 qui mlogit insure age if male==0, base(1) estimates store m2 suest m1 m2 test ([m1_Prepaid=m2_Prepaid]) ([m1_Uninsure=m2_Uninsure]) I think this code does what you want to do (in a very simple framework). You might need to adjust it accordingly.
