Hello everyone. I've been putting this off for a while, but I wanted to ask the community for article and book recommendation that would give me a good introduction to sabermetrics. As far as my background, I am not a stranger to statistics; although, I have only dealt with statistics in a sociological way (fatherst I have gotten is multi-regression). I'm also curious if there exist any baseball statistical datasets for STATA. I would love to play around with these data sets during winter break.
