CO:STA Sessions

The Colloquium for Statistical Analyses [CO:STA] is a forum to discuss quantitative methods that we apply in our research. 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.

Specifically, CO:STA hosts the following activities:

Workshops and presentations focusing on statistical methods and tools.

A reading group to work together through recent textbooks focusing on quantitative methods.

A speaker series with external guests but open to everyone willing to receive feedback with special emphasis of methodological issues

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!
