I recently ran two CFAs in Mplus. One model allows full covariances between all the factors while the second model restricts one of the covariance paths to zero. When I examine the output, however, both models have the same number of degrees of freedom and I don't understand why. Could you illuminate this issue?
Model 1:
DEM BY demss1c@1 demss2c demss3c;
SOM BY somss1c@1 somss2c somss3c;
LPE BY lpess1c@1 lpess2c lpess3c;
CYN BY cynss1c@1 cynss2c cynss3c;
ASB BY asbss1c@1 asbss2c asbss3c;
PER BY perss1c@1 perss2c perss3c;
DNE BY dness1c@1 dness2c dness3c;
ABX BY abxss1c@1 abxss2c abxss3c;
HPM BY hpmss1c@1 hpmss2c hpmss3c;
Model 2 adds:
LPE with HPM@0;
Thanks for your assistance. |

| Oh, by the way, I'm using MLMV estimation. |

| MLMV does not compute degrees of freedom in the regular way. See formula 110 of Technical Appendix 4. |
