Hello. I am using Mplus version 5.2 to run a simulation study comparing use of product moment correlations to use of polychoric correlations in EFA for categorical data. I am able to successfully, using your new instructions, run my simulations using Mplus with the monte carlo option for polychoric EFA using WLSMV as the estimator. However, I wish to use ULS as the estimator when using product moment correlations, as opposed to ML. When I attempt to do so, using the monte carlo option, Mplus gives me a warning message and then reverts back to ML as the method of estimation. Is there anyway I can get Mplus to use ULS in this situation?
