Structural Equation Modeling (SEM)
Peter Schmidt is Professor for Social Research at the University of
Giessen. Presently, Program Director at ZUMA (Centre for Survey
Research and Methodology, Mannheim, Germany), responsible for Social
Monitoring, (General Social Survey, Social indicators, and Microcensus
Data). His research interests are the foundations and applications of
structural equation models, analysis of panel data, and empirical
testing of rational choice theory. Applications include national
identity and environmental behavior, topics on which he has published
several books and papers.
The course will show how a causal theory can be represented by a path
diagram and translated into a structural equation model and how the
model can be estimated and tested with the AMOS computer program. In
the first part we will deal with measurement models relating single or
multiple indicators to latent variables. Furthermore different
specifications of measurement models are tested via confirmatory factor
analysis as a special case of a structural equation model. The second
part comprises both the structural and the measurement model. Topics
include recursive vs. non-recursive models for the structural part of
the model, treatment of panel data and multiple-group comparisons.
Special attention is given to the process of model modification.
The objective of this course is to show how structural equation
modeling can be used to develop and/or test both measurement models and
causal theories between latent variables. A further important aim is to
familiarize participants with the AMOS program. The program will be run
by graphical input via path diagrams (AMOS Graphics) and by command
language (AMOS Text).
