Dear Drs. Muthén and Muthén,
I am conducting CFA to verify the factor structure and psychometric features of my own instrument. And, I have a quick question about estimators, specifically MLM and MLR. My instrument consists of 23 items and uses a 5 Likert-scale. No missing data exists, but the assumption of multivariate normality is violated. Thus, I've been trying to figure out whether MLM or MLR should be used for my CFA. In my limited knowledge, both estimators could be used for my CFA and robust to the non-normality of data.
I tried both, and the results were similar with MLM estimator producing a little bit better CFI values and chi-squire values.
