Although, composite-based estimators always retrieve parameters of the postulated models via the estimation of a composite model, the computation of the degrees of freedom depends on the postulated model.
See: cSEM website for details on how the degrees of freedom are calculated.
To compute the degrees of freedom of the null model use .null_model = TRUE
.
The degrees of freedom of the null model are identical to the number of
non-redundant off-diagonal elements of the empirical indicator correlation matrix.
This implicitly assumes a null model with model-implied indicator correlation
matrix equal to the identity matrix.
A single numeric value.
