I've read a lot of statistics books, and most of them are poorly written. Their explanations are limited and often obscure. Their assumptions often go un-mentioned. That applies both to lower-level "statistical methods" books and higher-level theoretical books about mathematical statistics.<br><br>This book stands far above the pack. It explains concepts and techniques clearly, completely, and with all the steps included. I wish that I had started with this book instead of struggling, painfully and at great length, with the others.<br><br>One problem: I've been reading this book in the Kindle software for my iPod Touch. In the Kindle edition, some parts of the text are missing: not whole pages, but a paragraph or two here and there. Because I don't have the printed book (though I might spend the extra money to buy the printed version, too: this book is that good), I can't be sure if the omissions are just a problem in the Kindle edition. However, it seems like a reasonable assumption.<br><br>I would give this book a full five stars except for the problems in the Kindle edition. It's outstanding. I want to marry this book. :-)
