Structural equation modeling
Journals, discussion groups, interest
- AERA's SIG/SEM, the Special Interest
Group on Structural Equation Modeling of the American Educational Research
Association, promotes SEM in the American Educational Research Community,
mails out a newsletter and organizes contributed and invited paper sessions
at the Annual AERA Meeting. The affordable ($5/year; $8/2_years) Membership
in the SIG is open to all SEMers, and is a must for those that are already
members of the AERA.
Semnet, a mailing list maintained by Carl E. Ferguson, Jr. and Edward
Rigdon, provides a forum for discussions related to structural equation
Structural Equation Modeling: A Multidisciplinary Journal
Working group structural equation modeling, an informal group of mostly
Free SEM programs and technical
J. Curran's pages about SEM, with special consideration of longitudinal
growth modeling. Worked
examples show how to specify the same conditional and unconditional growth
models alternatively with the Amos, CALIS, EQS, HLM, LISREL, Mplus, Mx, and
(by John W. Graham and Scott M. Hofer) uses the EM algorithm to obtain maximum
likelihood estimates of means and covariances in the presence of missing data.
It can also impute missing values. There are separate EMCOV versions for DOS,
NT, and sun
systems to be downloaded as executables or self-extracting archive files.
The sun version comes with multiple-imputation facilities as discussed in
Joe Schafer's (1996) text book on multivariate analysis with missing data.
There is also a set of DOS-based
multiple-imputation facilities written by John Graham. Additional
information can be obtained from John
Graham. John Graham requests that you let him know by email if you download
a SEM program written by Mike Neale. Mx input is matrix-based, and the advanced
user will find the program's flexibility rewarding. The Windows and Unix
versions of Mx now have a graphical interface.
NOHARM, and COSAN programs are available at the Jefferson Psychometric
Lab, University of Virginia.
