GFI of baseline model #245

Closed fenglinhuoshan123 closed 1 year ago

fenglinhuoshan123 commented 1 year ago

I find that in AMOS(SPSS) the SEM result also gives GFI of baseline model. I really want to get this index, but found a bit difficulty for me to read about wls_obs object etc. Is there any way to generate baseline model GFI according the current fit parameters which can be easily extracted Tks!

You can fit any null model of interest, but the default independence-model specification can be obtained from the lav_partable_independence() function.

mod.null <- lav_partable_independence(fit)
fit.null <- lavaan(mod.null, data = HolzingerSwineford1939)
fitMeasures(fit.null, "gfi")
