An Introduction to Statistical Learning with Applications in R

Statistical learning refers to a set of tools for modeling and understanding complex datasets. It is a recently developed area in statistics and blends with parallel developments in computer science and, in particular, machine learning. The ?eld encompasses many methods such as the lasso and sparse regression, classi?cation and regression trees, and boosting and support vector machines. With the explosion of “Big Data” problems, statistical learning has become a very hot ?eld in many scienti?c areas as well as marketing, ?nance, and other business disciplines. People with statistical learning skills are in high demand. One of the ?rst books in this area—The Elements of Statistical Learning (ESL) (Hastie, Tibshirani, and Friedman)—was published in 2001, with a second edition in 2009. ESL has become a popular text not only in statistics but also in related ?elds. One of the reasons for ESL’s popularity is its relatively accessible style. But ESL is intended for individuals with advanced training in the mathematical sciences. An Introduction to Statistical Learning (ISL) arose from the perceived need for a broader and less technical treatment of these topics. In this new book, we cover many of the same topics as ESL, but we concentrate more on the applications of the methods and less on the mathematical details. We have created labs illustrating how to implement each of the statistical learning methods using the popular statistical software package R. These labs provide the reader with valuable hands-on experience
