fit {cSEM} | R Documentation |
Calculate the model-implied indicator or construct variance-covariance (VCV) matrix. Currently only the model-implied VCV for recursive linear models is implemented (including models containing second order constructs).

.object = NULL,
.saturated = args_default()$.saturated,
.type_vcv = args_default()$.type_vcv
)
.object |
An R object of class cSEMResults resulting from a call to |
.saturated |
Logical. Should a saturated structural model be used?
Defaults to |
.type_vcv |
Character string. Which model-implied correlation matrix should be calculated? One of "indicator" or "construct". Defaults to "indicator". |
Notation is taken from Bollen (1989).
If .saturated = TRUE
the model-implied variance-covariance matrix is calculated
for a saturated structural model (i.e., the VCV of the constructs is replaced
by their correlation matrix). Hence: V(eta) = WSW' (possibly disattenuated).
Either a (K x K) matrix or a (J x J) matrix depending on the type_vcv
.
