I saw this as follows: transition 1, you either got the right adress or not 1 : 2 3 4 5 transition 2, given that you got the right adress, someone is either there or not 2 3 : 4 5 transition 3, given that nobody is not at home, that could be because of short absense or long absense 2 : 3 transition 4, given that somebody is at home, that person can either participate or not 4 : 5 If you don't care about the difference between short absense and long absens ("both are deadways in comparison with being at home") then you can combine them. If you combine them, then you'll need to do so in your variable, you cannot just leave transition three out without changing your dependent variable. > Seqlogit coefficients are congruent with this only for the > sex variable, but not for age nor origin This is not a difference between -seqlogit- and -logit-, actually there can be none, instead the difference is due to the fact that in one you included interaction terms and in the other you did not.
