Multilevel ordered logistic regression with unequal slopes

[Demographer]

Hi, is there a way to do multilevel ordered logistic regression with unequal slopes with SAS? I want to model educational attainment (no high school, high school, postsecondary) with variables such as cohort, country cohort*country, religion, language and education of the mother. My understanding is that with a normal ordered logistic model, parameters for religion, language and education of the mother might be biased.

Yes, use the UNEQUALSLOPES option. See this note.

It is possible to do multilevel regression with proc logistic?

[StatDave]

If by "multilevel" you mean a random effects model with levels rather than meaning just multiple response levels, then no - you would need to use GLIMMIX to fit a "multilevel" model. I'm not aware that it allows separate slopes on the logits.

Yes, random effects models.
