How to Use RMSEA • Use the 90% Confidence interval for EA • Use The P-value for EA • RMSEA as a descriptive Measure • RMSEA< 0.05 Good Fit • 0.05 < RMSEA < 0.08 Acceptable Fit • RMSEA > 0.10 Not Acceptable Fit Ulf H. Olsson
Other Fit Indices • CN • RMR • GFI = 1-(Fm/Fn) • AGFI= 1 – (k(k+1)/(2df)) (1-GFI) • Evaluation of Reliability • MI: Modification Indices Ulf H. Olsson
Nested Models and parsimony • Modification Indices • chi-sq is chi-sq with df= df • Nested Models • Re-specification (Modification indices) Ulf H. Olsson
