This course focuses on the testing of causal
hypotheses in a cross cultural context. First the basic
reasoning and the connected statistical analyses will be
discussed for experimental, quasi experimental and
non-experimental designs. After that the course will concentrate
on non-experimental research. In that part the transformation of
verbal theories in testable propositions will be given a lot of
attention as an essential part of non-experimental research.
After that estimation, testing and correction of causal
hypotheses will be discussed.
After this general introduction of the SEM
approach we will introduce a general model for structural
equations which is a combination of an econometric simultaneous
equation model and a factor analysis model. This general model
allows the specification, estimation and testing of all known
linear structural equation models used. After that different
special cases of this general model will be discussed and
illustrated. Models for cross-sectional data, longitudinal data,
latent growth, multiple groups and multilevel data will be
discussed.
In large scale cross-national survey research
testing of causal hypotheses is confronted with two major
issues. The first is that one can only compare results across
cultures if the measurement instruments across the countries are
comparable. This problem will get a lot of attention because it
is essential in cross national research. The second issue is how
one can evaluate the equality or differences in effects across
countries given equality of measurement instruments. This can be
done in different ways: with interaction terms in pooled data,
with equality constraints in multiple group analysis or with the
use of random effects or multilevel models. All three
possibilities will be discussed and demonstrated in this course.
The data from the European Social Survey,
going on in more than 20 countries, provides sufficient
information to illustrate the possibilities and problems of
causal analysis in cross cultural context. So this data set will
be used to illustrate how one can cope in a proper way with
these issues.
The course will be a mixture of lectures and
exercises where the ESS data will be used. The idea is that
participants work in groups on a substantive problem and doing
so get familiar with the approaches presented in this course.
The substantive topics from the ESS which will be used in the
exercises will be social capital theory and theories about
migration in Europe .
In the conference after the course the
students are supposed to present the results of their analyses
while experts will be invited to introduce alternative
procedures for SEM approach to tackle the same or similar
problems. In this way the students will get a quite complete
picture of the different possibilities although the emphasis
will be on the SEM approach during the course. |
