When performing a multiplegroup cfa (using the groups = ""and groups.equal = "" arguments) and constraining loadings and intercepts to be equal, I don't get any modification indices regarding the intercepts when requesting the modification indices.
I fit a simple one factor model with four indicators from the "bfi" data set in the "psych" package. The code is as follows:
> modC <- '
F1 =~ A1 + A2 + A3 + A4
'
> fit.modC <- cfa(modC, data = bfi, group = "gender", group.equal = c("loadings", "intercepts"), estimator = "ML")
> fitmeasures(fit.modC, c("cfi", "tli", "rmsea", "srmr"), output = "text")
> modificationindices(fit.modC)
I hope someone can advise how to fix this.
