A welcome change of pace  
Beth and I were discussing a statistics problem the other day, and it turns out that no one had ever explained to her how to do a multiple-variable linear regression. (Possibly because it doesn't come up all that often.)

So I showed her the derivation and method for solving one, and she got it very quickly. I've grown accustomed to having to work hard explaining math, and it was break to just have someone get something more or less immediately.

I've been reading Prof. Cosma Shalizi's course-notes from 36-402: Undergraduate Advanced Data Analysis at CMU. They are really excellent writeups!! The lecture on additive models, in particular, has been eye-opening about the shortcomings --- and oft-easy fixes, given that R and its ilk are widely available --- of linear regression.

Looks like interesting stuff. Thanks for the pointer.
