Is fmin in fitMeasures() what you need?

E.g.,

library(lavaan)

example(cfa)

fitMeasures(fit, "fmin")

Thanks for your help. I need it to check the value of chi-square and compare between softwares. Just a personal curiosity.

Then you should know that (for historical reasons), fmin = 1/2 * F,
where F is the textbook discrepancy function. So to compute chi-square
from fmin, you should use 2*N*fmin (if normal ML), or 2*(N-1)*fmin for
other estimators.

Thank you very much for your  explanation.

Asghar.
