As you may know, today is Pi Day, when all good nerds take a moment to thank the geeks of antiquity for their painstaking work in estimating this marvelous mathematical constant. It is also a great opportunity to thank contemporary geeks for the wonders of modern computing, which allow us to estimate pi to near

Last time, I covered ordinary least squares with a single variable. This time, I'll extend this to using multiple predictor variables in a regression, interacting terms in R, and start thinking about using polynomials of certain terms in the regression (like Age and Age Squared). This should be a pretty straight forward tutorial, especially if you've got...
