Research direction
Start in factor_analyzer/confirmatory_factor_analyzer.py around line 379, where the existing fit measures are reported. Review how the current chi-squared result is computed and identify the inputs needed for CFI and RMSEA. Done means CFA results expose correct CFI and RMSEA values alongside the existing measures.
Written by the indexing model from the issue text.
Description
My (quite inexpert) understanding is that CFI and RMSEA are the goodness-of-fit measures par excellence when it comes to CFA. It seems that Chi-squared is also useful.
Would it be possible to add these metrics, like around here? https://github.com/EducationalTestingService/factor_analyzer/blob/main/factor_analyzer/confirmatory_factor_analyzer.py#L379
