I am fitting a structural model, from a complex survey data consisting of 2933 usable cases. My DV is categorical, so are almost all of my IVs (except two)

Here are my analysis commands.

Type = Complex;
Estimator = WLS;
parameterization = theta;

My model fit results:
Number of Free Parameters 107
Chi-Square (df=20; P-value=0.0175) = 35.511

RMSEA (Root Mean Square Error Of Approximation)

Estimate 0.016
90 Percent C.I. 0.007 0.025
Probability RMSEA <= .05 1.000


CFI 0.995
TLI 0.970


This is the results of my my full model. I am inclined to report this model, but only interpret the significant path coefficients. The trouble is my chi-sq is significant, but the RMSEA and CFI/TLI seems acceptable.

1. Can i go ahead and use the model, despite the significant chi-square.

2. No SRMR values were reported - is there anyway to obtain this?

Thanks - cY

This looks like a well-fitting model to me. The p-value is pretty good given the large sample.

If you use Version 8 and SRMR values are not reported, they are not available and may not be easy to compute yourself.
