How to judge the goodness of fit of gsem model (generalized structural equation model) in stata?

[Qun Wang]

Dear Experts,

I know that the command of judging sem (structural equation model) is "estat gof, stats(all)". Then what is the command of the goodness of fit of gsem model (generalized structural equation model) in stata. Thanks!

Unfortunately, gsem provides only a handful of goodness of fit statistics, focused on comparative fit measures. These include the chi-square test, AIC, and BIC. sem, on the other hand, includes a larger number of fit statistics, including SRMR, CFI, TLI, etc. This means that with gsem models, you are left to compare either nested models via lrtest or AIC/BIC comparisons.
