This book appears to be written for people who already completely understand statistics, in which case they probably don't need this book. I'm someone with a undergrad-level understanding of statistics and astronomy and this book does little to further my understanding of either. I wish the authors had taken more care in explaining the subject matter and notation. I didn't expect this to be an introductory statistics book, but IMHO the word "practical" should not be in the title. Unless you have an advanced understanding of statistics, this book is not helpful.
