I am using ordinal panel data data and I just use ologit and the cluster command to account for the correlation of individuals over time. There is also the gologit2 - which allows you to do a generalized ordered logit.

Subject: Re: st: model for longitudinal ordinal data
Thanks a lot James.
I researched -gllamm- but I was not sure if one can specify the type of covariance sturucture in it. I have three time points only and wanted to specify cov(uns).
The -ologit- with the vce(cluster id) should work.

Subject: Re: st: model for longitudinal ordinal data
There are three programs that can be used to fit random effects
ordinal probit models in Stata:
-reoprob-
-regoprob-
-gllamm-
-regoprob- is capable of fitting generalized random effects ordinal
probit models that do not entail the proportional odds assumption.
-gllamm- can also fit random effects (and random coefficients) ordinal
logit models.
Finally, you may consider simply fitting an ordinal logit or probit
model to your data with a cluster-robust variance estimator using
-ologit- or -oprobit-, respectively. In each case, you would need to
use the "cluster(subject id)" option.
Hope that this information is helpful.
Regards,
Jim
