CFA using PROC CALIS SAS 9.4

[Mynalvez]

Hello SAS Community:

Just wanted to ask about the chi-square dF computed from PROC CALIS fitness statistics (Fit Summary Table). I run a confirmatory factor analysis (CFA) with 7 observed items and 2 latent factors. I fixed all latent factor variances to 1.00. My Fit Summary Table yields a chi-square value of 18.52; dF=13, and a p-value of 0.1387. My question is: how is the number of dF calculated? I ask as I am unable to reconcile this (i.e., dF=13) with the formula: [p(p+1)]- [#error variance + #of factor loadings estimated + #latent factor covariances]. Thanks!
