sab-R-metrics: Basic Applied Regression (OLS)

Today, I'll again be using a new data set that can be found here at my website (called 'leagueoutcomes.csv'). The data set includes the standings results of the 2009 season for MLB along with average game attendance by team. I'll use this to go over some basic regression techniques and tools in R. Hopefully this...
