Hello,
I’m examining CFA model invariance using the lavaan package in R. I’ve run an
analysis to test “strong” model invariance (e.g., fixing loadings and
intercepts to be equivalent across groups) but cannot seem to retrieve
modification indices for freeing intercept parameters.
Here is sampl
i tried the semPlot but it flopped. various other packages also did not
perform. i will try the DiagrammeR package and revert.
meanwhile, i tried going to the onyx package and its neat, though i have
yet to spend some time on it to familiarise myself with the nuts and bolts
of the process.

Have you considered using the semPlot package? It works nicely with
lavaan models (among other sem packages). There is also the DiagrammeR
package.

Does the package semPlot not do what you want? I notice that you got
an error when you used library(semPlot) because you don't have all the
dependencies installed. When you have semPlot working, it should be
able to produce a graphical output of the results, including
'covariance arrows'.

I've run SEM using lavaan and after I used summary(myfit) I saw the

Dear Andrew,
Maximum likelihood estimation with missing data typically makes some
rather strong assumptions. If I am not mistaken, the default
covariance coverage in Mplus is .05, the fact that you need to set it
lower suggests you have some combinations of variables with less than
5% jointly pre

That's

The model is almost surely misspecified; check also for missing covariances.
