Millsap's SEM Page
This webpage contains links to resources for
Structural Equation Models (SEM) and for statistical
issues in their use. For individuals who like to participate
or lurk in a listserve environment, you may wish to join
the SEMNET listserve. You can find out how to join
by going here.
Hats off to Carl Ferguson and Ed Rigdon for their superb efforts
in maintaining this listserve.
Software Links
Given that you aren't going to make much progress in SEM without
software resources, here are some links to major software sites,
in no particular order.
- Scientific Software's
LISREL,
with Karl Jöreskog's Corner.
- Bengt and Linda Muthén's
Mplus site.
- Peter Bentler's
EQS site.
- Michael Neale's
Mx site (this one is free!).
- AMOS, now part of SPSS
and no longer part of Smallwaters.
- STREAMS, a meta-program
that works with LISREL, Mplus, or EQS to facilitate programming.
- GLLAMM, stata programs for
generalized linear latent and mixed models.
Or, you could write your own! If you really want to learn how it is
done, there is no better way. For a great description of how to get
started, see:
Cudeck, R., Klebe, K.J. and Henly, S.J. (1993).
"A simple Gauss-Newton procedure for covariance structure analysis with
high-level computer languages", Psychometrika, 58 (2): 211-232.
Other Annotated Links
Here are some additional links to pages that might be of interest to
you if you are learning about SEM.
- Univ of Texas-Austin
IT Software Tutorials.
These pages provide guidance on the use of LISREL/PRELIS, Mplus, AMOS and other
statistical software. My students have found these pages to be useful.
- Jason Newsom's
SEM reference list.
A really nice list of references, sorted by topic, on all aspects of SEM.
- Web page for
Working Group SEM in Europe.
Jost Reinecke maintains these pages.
- Judea Pearl's
home page, with links to
material on his Causality book and papers.
- Ken Bollen's
home page, with links to
the Carolina SEM group.
- The
SEM Journal.
An academic journal devoted to SEM theory and applications.
- David Kenny's
web page on SEM.
David's page has a nice tutorial on SEM based on his class on the topic. Full of good
examples.
- Bengt Muthén's
web page, with links
to publications and Mplus material.
- Michael Browne's
web page, with software downloads
for dynamic factor analysis, direct product analysis of MTMM matrices, exploratory factor
analysis, analysis of circumplex correlation matrices, and other topics.
- Patrick Curran's
web page, with a resource
list for longitudinal methodology and applied statistics.
- David MacKinnon's
Research in Prevention Lab,
with information on mediation modeling in SEM.
- Robert MacCallum's
web page, with downloads of material from some of
his papers, including power analysis programs from MacCallum, Browne, and Sugawara (1996).
- Web page of the AERA
Special Interest Group on SEM, with a list of
web resources on SEM. AERA is the American Educational Research Association.
- Jim Steiger's
web page, with downloads of useful software and
a list of relevant publications. The software includes programs for the noncentral chi-square.
- David Garson's
web page, with a
large tutorial on SEM, a bibliography, and an FAQ list.
- The Tetrad Project
homepage, with software downloads and information related to this exploratory causal modeling
approach.
- Robert Ping's
web page with information on models incorporating
latent variable interactions.
- David Dowe's
Mixture Modeling page,
a rich source of information and links on all aspects of mixture modeling.
Multigroup CFA with Ordered-Categorical Indicators
For those of you who are trying to conduct multigroup CFA with ordered categorical variables in
Mplus, I have created a zip file containing all of the programs used to generate the examples
found in Millsap and Tein (2004). You can
download the zip file. As
a key to the files contained in the zip file, you will want to
view this word doc, which
describes which files go with which examples in the paper. I hope that this will help many of
you who are struggling with the syntax for these complex models.
