Degrees of Freedom 5**
P-Value 0.0000
* The chi-square value for MLM, MLR, MLMV, WLSM and WLSMV cannot be used for
chi-square difference tests. MLM and MLR chi-square difference testing is
described on page 360 in the Mplus User's Guide.
** The degrees of freedom for MLMV and WLSMV are estimated according to
formula 110 (page 358) in the Mplus User's Guide.
