Usage

mgcfaDiagnose(lavaan.model, output = c("overall", "neg.var", "mi"))

lavaan.model

Fitted lavaan multiple group model.

output

A character list of what diagnostics should be computed. #'

overall: Prints chi-sq, CFI, RMSEA, and SRMR
neg.var: Checks if there are negative variances of latent variables, if yes, identifies the groups and prints them.
mi: Aggregates modification indices across groups, finding the most impactful. Also prints the top part of sorted table of modification indices.
constraints: Optional. Applies and prints lavTestScore_clean.
