Dear Lavaan Group
I am doing SEM with mixed type data including categorical (ordinal and binary)variables but also interval variables. Unfortunately, there are no Fit Criteria for Good Model Fit in such a case (so far I used the well-known criteria for continuous data with ML estimator as orientation). According to https://www.statmodel.com/download/Yudissertation.pdf I would need a Simulation Study to evaluate the Criteria for Good Model Fit since I am using WLSMV estimator and mixed type data. Is this possible in Lavaan? If yes, how would this work? If no, what would be other alternatives to just using the “wrong” criteria?
Does anyone have experiences in this topic?
