Calculate the average variance extracted (AVE) as proposed by
Fornell and Larcker (1981)
. For details see the
cSEM website

```
calculateAVE(
.object = NULL,
.only_common_factors = TRUE
)
```

## Arguments

- .object
An R object of class cSEMResults resulting from a call to `csem()`

.

- .only_common_factors
Logical. Should only concepts modeled as common
factors be included when calculating one of the following quality critera:
AVE, the Fornell-Larcker criterion, HTMT, and all reliability estimates.
Defaults to `TRUE`

.

## Value

A named vector of numeric values (the AVEs). If `.object`

is a list
of `cSEMResults`

objects, a list of AVEs is returned.

## Details

The AVE is inherently tied to the common factor model. It is therefore
unclear how to meaningfully interpret the AVE in the context of a
composite model. It is possible, however, to force computation of the AVE for constructs
modeled as composites by setting `.only_common_factors = FALSE`

.
