Juea Pearl's Causal Analysis Blog

Judea Pearl is a big name in causal analysis. His book Causality: Models, Reasoning and Inference is already a classic (a second edition is scheduled to come out in October 2009). In contrast to Donald Rubin, Judea Pearl takes a graphical approach to causality. The basic idea is to represent conditional dependencies in a path diagram. Professor Pearl writes a blog on causality that can be found here.
