Dear Anthony, I'm not sure what you mean by a "stacked model comparison." If you mean a model fit to multiple groups, then the answer is no. If you mean comparison of nested models, then anova() can be used to get a LR test. See ?anova.sem.
I hope this helps, John ------------------------------ John Fox, Professor Department of Sociology McMaster University Hamilton, Ontario, Canada web: socserv.mcmaster.ca/jfox > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On > Behalf Of Anthony Dick > Sent: January-06-09 2:56 PM > To: r-help@r-project.org > Subject: [R] R SEM package > > Does anyone know if the sem package in R can implement a stacked model > comparison, for example as in LISREL or AMOS? > > Thanks, > > Anthony > > -- > Anthony Steven Dick, Ph.D. > Post-Doctoral Fellow > Human Neuroscience Laboratory > Department of Neurology > The University of Chicago > 5841 S.
