 The Elements of Statistical Learning: Data Mining, Inference, and Prediction, Second Edition (Springer Series in Statistics) $89.95 I originally bought this book for coverage of some topics about which I know nothing. But having had it for just a week, I have been more impressed with what I have learned about stuff that I thought I knew. The material in Chapter 7 is one of several cases in point. The discussion of cross validation is great, and the way it is related to other aspects of the model selection problem is masterly. More generally, the book manages a nice balance between theory and application, and its scope is truly impressive. Thanks to authors and publisher.

Statistical Inference $201.95 I took my first Grad Stats course from an instructor that was teaching this course for the first time. He decided to use at least 5 different books - never fully explaining anything in any of them. This was a very difficult subject to understand with no application or instructor explanation. |
