Dera Drs. Muthen, I am running a two-part cross-sectional model. If I do not specify an estimator, the default estimator is WLSMV. However, I thought that, because the MCAR assumption is not met for two-part modeling, the estimator ML had to be used. I want to test for indirect effects in the context of the 2-part model and, thus, would like to use WLSMV as the estimator, if possible. Can I use WLSMV as the estimator w/ cross-sectional data and 2-part modeling?
