Hi! I have some questions about prior used for “fscore” from MCMC and WLSMV. I saw previous discussion "with WLSMV it is actually MAEP (maximum a posteriori) with a normal prior that is used". What are the mean vector and covariance matrix of that normal prior? Are they estimated by the item response model?
Also, what prior is used for fscore from MCMC? We are trying to compare the factor score estimates from MCMC and WLSMV. Are there any ways to use non-default priors so that we can use same prior in MCMC and WLSMV? |
