Title: Frustrated
Review: Firstly, I am not stats guru, a mere mortal trying to get through a top-10 MBA program. I picked this book (and the companion text) to extend my knowledge, and it is helping. Tough for the gifted amateur, but interesting and the depth of the analysis truly helps.Major negative comment : The manual often provides one sentence answers to mathematical questions. For example : "....slight improvement in the model." But this is not helpful. It lacks truly worked answers to the questions; which is essential to help those who are struggling to get to the right level.This is not a limited observation, it is the trend and considerably more work could be done to explain how answers were derived, as it also helps find out why an answer might not be correct.As for the up side. All chapter questions are answered and the FTP site provides raw data files. This is greatly appreciated. In balance, the weaknesses are significant.
