(Egregious self-promotion: I'll be leading a day-long workshop at next year's RPM in Washington, DC.) I wasn't looking for a presentation on hierarchical models, but there one was. The fantastic Jim Guszcza has a great

Over the course of the next few days, I'm going to try to find enough time to build up a reasonably simple simulation of insurance exposure and claims. I'll be taking a hierarchical view of the underlying process. As with pretty much everything that I write about, I'm writing about it as I'm learning about
