Summary
The chapter began with two important variations of the CART technique, looking at the bagging technique and random forests. The random forest particularly is a very modern technique invented in 2001 by Breiman. The goal of the chapter was to familiarize the reader with these modern techniques.
Together with the German credit data and the complete revision of the techniques with the low birth weight problem, I hope that you benefitted a lot from the book, and have gained enough confidence to apply these tools to your analytical problems.
