## Degrees of freedom

### Description

Calculate the degrees of freedom for a given model from a cSEMResults object.

### Usage

```
calculateDf(
.object = NULL,
.null_model = FALSE,
...
)
```

### Arguments

`.object` |
An R object of class cSEMResults resulting from a call to |

`.null_model` |
Logical. Should the degrees of freedom for the null model
be computed? Defaults to |

`...` |
Ignored. |

### Details

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.

### Value

A single numeric value.
