Just a simple question regarding GFI when comparing groups in Lisrel - I thought GFI should be between 0 and 1 where 1 would mean perfect fit.
How come do I get results over 1 when comparing groups (measurement inequivalence; LX=IN)? Is then 1.08 "same" goodness-of-fit as 0,92?
Here is the example output:
Group Goodness of Fit Statistics
Contribution to Chi-Square 40.176
Percentage Contribution to Chi-Square 17.523
Root Mean Square Residual (RMR) 0.0432
Standardized RMR 0.0432
Goodness of Fit Index (GFI) 1.019
