Dear Dr Muthen,
I would like to run a CFA and SEM with ordinal variables measured on a 1-7 Likert scale and a categorical variable (with 5 categories).
Mardia’s test indicates that the data are not multivariate normal. My questions concern estimation methods and approaches to modelling.
1. Do I run a CFA with both ordinal and categorical variables (using the WLSMV estimator) or
2. Can I a run a CFA with just the ordinal variables (the categorical variable is excluded) using the MLR estimator and then with the structural model, adding back in the categorical variable, run a full model (with both ordinal and categorical variables) using the WLSMV estimator.
