Dear statalisters,

can the fitstat command be used to compare the goodness of fit of 2 models with de same independent variables but slightly different dependant variables?

Example:

if y1: =1 if A and B
       =2 if A or B
       =3 if neither A nor B

and y2: =1 if A and B
        =2 if A not B
        =3 if B not A
        =4 if neither A nor B


how could I show that using y1 , for example, gives better explanation than y2

Are you basically asking whether it is ok to combine categories 2 and 3 in y2 into a single category? If so, Long & Freese's

mlogtest, lrcombine (or else mlogtest, combine)

might give you what you want. If you don't already have the program (or have one of the old and outdated versions that is floating around) then type
