Re: st: longitudinal ordinal regression
Perhaps not exactly what you are asking, but the econometrics program
call Limdep has ordinal logit and probit panel models.

Hi,
I-emailed statalist about a month back regarding longitudinal
ordinal regression in STATA (as I couldn't find anything such as `xtologit').
A few people recommended that I should use GLLAMM or ologit
(with `cluster id' option). But there is no option to specify the
type of covariance structure (unstructured, ar1 etc.) on either of
them if I am not wrong. I think the cluster(id) option for ologit
(or i(id) for GLLAMM) are just nesting the observations by their
respective ids.
I was wondering if anyone can point out some other models which
could take care of this problem (specifying covariance structure in
a longitudinal OLR)?
Thanks,
Joey
