Query: cryptic, brief, leaves you wanting much more...

Unfortunately, this book was used as the textbook in a mathematical statistics class taught by the author at UC Davis, which I was enrolled in. I found the book to be extremely brief, cryptic, and failed to even begin to explain the subject at hand in any kind of depth. I am an engineering student and am accustomed to technical material. This is the kind of textbook that gives the sciences a bad image. Being rigorous does not imply that you must be cryptic. Statistics is an exciting subject and this book utterly fails to inspire, explain, and enlighten.
