I didn't think it was so simple, but I did not find the question very clear.
Are the linked observations defined when zdup and edup are greater than zero
or on some other criteria? Do the linked observations comprise one group
and the unlinked observations a second group? Or does each of the unlinked
observation comprise a separate group?....Anyway, I think your
interpretation is correct and I am glad you had a solution.
