Symposium "Causal effects - Designs and Analysis"

From July 17 to 19, 2008 was held a conference at the "Altes Schloss Dornburg" near Jena.

Goals of the Symposium were

1. Bringing together different traditions of analysis of causal effects (regression-based analyses, analyses based on propensity scores, analyses with instrumental variables), discussion of the state-of-the-art,
2. Discussion of non-standard designs and problems (missing data, non-compliance, multilevel designs, regression discontinuity designs),
3. Meeting of leading proponents of different fields where the analysis of causal effects plays an important part.

Organizational structure

The structure of the conference was closely followed the "Symposium on Causality 2006". There were held 7 focus presentations by leading proponents in different fields of causality research. Each focus presentation was discussed and supplemented by two invited discussants, followed by an open discussion among all participants. There was also room for participants to present their own research in short presentations and poster sessions.

For further information, please visit the website of the Symposium on Causality 2008.
