Dear Linda and Bengt,

Is it possible to estimate two-level model with cross-classified random effects? For example, in educational research, kids are nested within primary school and secondary school, but primary and secondary schools are not nested within each other but cross-classified. Some references on this topic can be found in Leyland and Goldstein (2001), chapter 7, or Raudenbush and Bryk (2002), chapter 12.

Thanks!

Shige

Crossed random effects are not implemented in the current Mplus version, so unless one can think of some latent variable trick, this cannot be done yet.

If you don't have too many categories and have a lot of data, you could conduct a multigroup analysis and then constrain parameters across groups to test for the effects of the classifications.

Hi:

It looks like it's possible to do CCREMs in Mplus now, but I'm having some difficulty replicating a particular model.

I'm looking to run a cross-classified model which has no predictors but has two random intercepts. So using the terminology of the Mplus manual and the example Michael posted above:
-->There would be no "within" model
-->The only things influencing y would be level2a (primary school) and level2b (secondary school), which would vary randomly

Is this possible in the new MPlus framework? If so, how would I code it?

If you have no covariates, you would not have random intercepts. You would have random means.

MODEL:
%WITHIN%
y;
%BETWEEN level2a%
y;
%BETWEEN level2b%
y;

Thanks! One other question--if I wanted to get the random means for each group, is there a particular output I would request or operation I would perform?

Thanks in advance for your help.

No.
