I have a question. I am testing a model in which I have five dummy outcome variables. Beacuse I want them to have the same reference category, I want to let the residuals between these dummy variables be correlated. Which commando can I use best in Mplus?
You should use either the NOMINAL option if you have a six-category unordered categorical variable or the CATEGORICAL option if you have an ordered categorical variable.

Thanks for your quick answer.
Ideally, I would like to stick to my - separate - dummy variables because, then, I can investigate directly for which categories effects are different (for one six-category variable, when you have found an effect you can only state that there is an effect on this variable, but then you still do not know for which categories effects are different).
If I decide to stick to my five separate dummy variables, I want them to have the same reference category. In that case, which commando can I use best in order to have the residuals between these dummy variables be correlated?
