It conducts the second stage analysis of the uniR analysis by fitting structural equation models on the average correlation matrix.
uniR2mx(x, RAM = NULL, Amatrix = NULL, Smatrix = NULL, Fmatrix = NULL,
model.name=NULL, suppressWarnings=TRUE, silent=TRUE,
run=TRUE, ...)
uniR2lavaan(x, model, ...)
A fitted object returned from mxRun
or sem
.
An object of class uniR1
from
uniR1
.
A RAM object including a list of matrices of the model
returned from lavaan2RAM
.
If RAM
is not specified, an Amatrix
is
required. An asymmetric matrix in the RAM specification with
MxMatrix-class
. If it is a matrix, it will be
converted into MxMatrix-class
by the as.mxMatrix
function.
If RAM
is not specified, an Smatrix
is
required. A symmetric matrix in the RAM specification with
MxMatrix-class
. If it is a matrix, it will be
converted into MxMatrix-class
by the as.mxMatrix
function.
If RAM
is not specified, an Fmatrix
is
required. A filter matrix in the RAM specification with
MxMatrix-class
. If it is NULL
(the default), an
identity matrix with the same dimensions of Cov
will be
created. If it is a matrix, it will be converted into
MxMatrix-class
by the as.mxMatrix
function. It is not required when there is no latent variable.
A string for the model name in
mxModel
. If it is missing, the default is
"UniR2".
Logical. If TRUE
, warnings are
suppressed. It is passed to mxRun
.
Logical. An argument to be passed to mxRun
Logical. If FALSE
, only return the mx model without
running the analysis.
A model specified using lavaan syntax see model.syntax
Further arguments to be passed to either
mxRun
or sem
. For
sem
, fixed.x=FALSE
is passed automatically.

This function implements the univariate r approach proposed by Viswesvaran and Ones (1995) to conduct meta-analytic structural equation modeling (MASEM). It treats the average correlation matrix as if it was a covariance matrix in fitting structural equation models. The harmonic mean of the sample sizes in combining correlation coefficients is used as the sample size in fitting structural equation models. It is included in this package for research interests. The two-stage structural equation modeling (TSSEM) approach is preferred (e.g., Cheung, 2015; Cheung & Chan, 2005).
