i am trying to conduct cfa anaylsis using R studio however, instead of giving me all the fit indecisive i am supposed to get , even with the summary function i dont get the GFI | AGFI | NFI | NNFI | CFI | RMSEA . can any one please help me with this issue
Estimator ML
Optimization method NLMINB
Number of free parameters 25
Number of observations 275
Model Test User Model:
Test statistic 228.937
Degrees of freedom 41
P-value (Chi-square) 0.000
Did you set fit.measures=TRUE in summary function?
Eg: summary(cfa_model, fit.measures=TRUE,standardized=TRUE)
İf you only want to get measures you can use fitMeasures() function from lavaan package.
Eg: fitMeasures(cfa_model)
By default, lavaan will always fix the factor loading of the first indicator to 1. In order to fix a parameter in a lavaan formula, you need to pre-multiply the corresponding variable in the formula by a numerical value. This is called the pre-multiplication mechanism.
