  1. Thanks to my colleague Justin for suggesting the spin on $%?&# My Life!

    Explanation time: the expression with X and Y is the matrix notation for the way that regression coefficients are calculated when using the ordinary least squares (OLS) technique.

    OLS is by far the most commonly used regression technique. It's not cutting edge, but it still does a pretty good job most of the time--just like some of my favorite old school songs.
