In this weblog, we will report on recent research and ongoing half-baked ideas, including topics from our research groups on Bayesian statistics, multilevel modeling, causal inference, and political science. See Andrew Gelman’s webpage for more background.

We will also post on anything that interests us that relates to statistical ideas and their applications.

Contributing to the blog will be Samantha Cook, Andrew Gelman, and various of Andrew’s students and colleagues who would like to add things.

Comments will be helpful to suggest open problems, to point out mistakes in the work that we post, and to suggest solutions to some of the open problems we raise.
