Hi.
As far as I understand, it is possible to estimate concordance of a dichotomous trait through a liability threshold model. If so, could anyone guide me a bit how to do that? I'm totally lost and don't know how to incorporate that into a saturated model.
I'm interested in pairwise and casewise concordance.

Best,
Julia
