hi, I am a beginner using Mx open packages, so I do not quite understand. I have run my program. output is given as attached.
The value of RSMEA, CFI and TLI its very ugly because its value doesn't meet either criteria . What can I do in advance to improve the model?
thank you.

Seems like either you are not testing the model you think you are, or the model is a bad fit...

Probably need to see the script as well

You could try fitting several alternative models and compare the fits of the alternatives.


myFavoriteModel <- mxModel(...)
alternativeModel1 <- mxModel(...)
alternativeModel2 <- mxModel(...)
alternativeModel3 <- mxModel(...)

mfm <- mxRun(myFavoriteModel)
am1 <- mxRun(alternativeModel1)
am2 <- mxRun(alternativeModel2)
am3 <- mxRun(alternativeModel3)

#If models are nested
mxCompare(mfm, am1, am2, am3)
