Hi, I am modeling count outcome using a negative binomial regression on one latent factor and several observed covariates. It seems that besides the AIC and BIC, Mplus doesn't provide any absolute mode fit index. Any suggestions? Thanks!
Chi-square and related fit statistics are not available for this model. In this case, nested models can be compared using -2 times the loglikelihood difference which is distributed as chi-square. Non-nested models with the same set of dependent variables can be compared using BIC.
