I'm using the lavaan package for my sem models. In the next months, I'll need to fit a mixed, multilevel sem models. However, lavaan doesn't fit this kind of model yet. Does anyone know of an alternative package?
Thanks.
Hi Paras.
I've seen xxM package but it's only work in windows and I'm an linux user.
Hi,
MPlus, made by Bengt and Linda Muthen can fit multilevel SEMs. They have a very usable manual available online and excellent help via their online forums. I believe the student version is free to download. It can also do things like multilevel mediation.
If path analysis, a special type of SEM, can suit your needs, the method of Bill Shipley is excellent:

Hallo Jose',
Go to CRAN, download the R package "sem"
Good luck
Dr John MM
I too endorse Mplus. However, particularly promising is gsem (Generalized Structural Equation Modeling) by the most recent version of Stata (Stata 13). It can allow the estimation of models to handle multilevel analysis while incorporating Bernoulli procedures.
You can also try LISREL 8.8. I have used it and found it fast and effective for SEM analysis. The demo version can be downloaded at
