measEq.syntaxclass  R Documentation 
This class of object stores information used to automatically generate
lavaan model syntax to represent userspecified levels of measurement
equivalence/invariance across groups and/or repeated measures. See
measEq.syntax
for details.

as.character 

package
character
indicating the software package used to
represent the model. Currently, only "lavaan"
is available, which
uses the LISREL representation (see lavOptions
).
In the future, "OpenMx"
may become available, using RAM
representation.
model.type
character
. Currently, only "cfa" is available.
Future versions may allow for MIMIC / RFA models, where invariance can be
tested across levels of exogenous variables explicitly included as
predictors of indicators, controlling for their effects on (or correlation
with) the common factors.
call
The function call as returned by match.call()
, with
some arguments updated if necessary for logical consistency.
meanstructure
logical
indicating whether a mean structure is
included in the model.
numeric
character
vector naming numeric
manifest indicators.
ordered
character
vector naming ordered
indicators.
parameterization
character
. See lavOptions
.
specify
list
of parameter matrices, similar in form to the
output of lavInspect(fit, "free")
. These matrices
are logical
, indicating whether each parameter should be specified
in the model syntax.
values
list
of parameter matrices, similar in form to the
output of lavInspect(fit, "free")
. These matrices
are numeric
, indicating whether each parameter should be freely
estimated (indicated by NA
) or fixed to a particular value.
labels
list
of parameter matrices, similar in form to the
output of lavInspect(fit, "free")
. These matrices
contain character
labels used to constrain parameters to equality.
constraints
character
vector containing additional equality
constraints used to identify the model when ID.fac = "fx"
.
ngroups
integer
indicating the number of groups.
