Prof. Muthen

Can we run Melton and Liang's GEE approach In MPlus, (mine is MPlus version 3.12), the reason I'm asking so because in your 1997 article, u have done a comparative study of ur proposed estimator in comparison to their GEE ... if we can then how

In my model, indicator variables are all ordered categorical?

Thanks and regards

Dear Proffesor ... In connection to my earlier message ... I forgot to mention the main reason why I'm looking for Melton and Young's(M&Y) GEE approach ... in ur 97 article, page 24, you have mentioned M&Y's approach performed better than Robust WLS particularly when the sample size is small ... I have two sample size, one is 240 and the other one is 139 (my models are SEM with covariates and categorical indicator outcomes variables)

thanks and regards

sorry ... the word "Professor" has been misspelt :-)

No, Mplus does not use the GEE approach. We don't feel there is enough of an advantage over robust WLSMV. We also have full-information maximum likelihood for categorical outcomes which theoretically should perform as well if not better than GEE.

Thanks... one more quick question

what should be our estimator choice in order to run full-information ML for Categorical Outcome ... is it ML, MLR or MLF (page 366, MPlus manual)

I suppose my understanding could be wrong, please correct it if it so.... isnít the case that we use Limited Information ML (I mean separate equation wise) for the first two-stages of 3-stage estimation procedure propounded by Dr. Muthen (1983,1984)

thanks and regards

Our default estimator for maximum likelihood is MLR.

Your understanding is correct.

Thanks Madam ... have a nice weekend
