The Colloquium for Statistical Analyses [CO:STA] is an informal forum to discuss quantitative methods that we apply in our research. CO:STA presents an opportunity for researchers of all levels to present their work in progress with special emphasis of methodological issues, or to simply visit the colloquium and learn about new methods and alternative strategies to answer pressing questions. Reflecting the set-up of the WZB, particular applications include examples from political science, economics and sociology. The colloquium is open to all WZB researchers as well as to external guests. Our newsletter informs about upcoming sessions.

If you wish to present and discuss your research at CO:STA, if you have suggestions for interesting topics that should be covered, or if you wish to be registered for the newsletter – feel free to drop an e-mail to the CO:STA team!
