The default for categorical variables is the weighted least squares estimator for which BIC and AIC are not available. You would need maximum likelihood estimation to obtain these values. With categorical variables and maximum likelihood estimation, each factor requires one dimension of integration. This could become computationaly demanding.

Thanks so much for the prompt response! I specified with ESTIMATOR=ML; But the BIC and AIC still don't show up...Am I doing anything wrong?
