这个分析指南说的好，
This book is thus organized for a business analyst rather than a statistician. It will
not help you get a better grade on your graduate school thesis, but it will definitely
help you get, or retain, a job in analytics. If you are a student studying R, it should
help you do your homework faster.

本书是写给商务分析人的，不是写给统计学家的，这就意味这本书适合我这样的不想太多写代码的人，大家下载看看吧
