I was wondering what the assumed null model is in MPLUS for a growth model? In other words can I trust the incremental fit indices like the CFI for a growth model or do I need to first estimate a null then a saturated model and calculate the CFI by hand? e.g. [(LR_null-DF_null)-(LR_sat-DF_sat)]/(LR_null-DF_null)

Thanks for any help

For CFI and TLI, the baseline model is means and variances for both exogenous and endogenous variables and covariances between the exogenous and endogenous variables.
