review
| Customer Rating: | hard cover, the textbook is always in good condition
useful content, the most widely used textbook in statistics
price is bit high though, it is still worthy buying |
Worst textbook I've had the misfortune to read
| Customer Rating: | | I understood less about probability after reading the first few chapters of this book than before reading it. The wording is extremely vague because the author tries too hard to generalize, using abstract terms such as n, r, x, etc to describe everything and leaving you to decide for yourself which part of the problem these variables apply to in the practice problems (less than half of which have solutions, none of which are comprehensive). Thank goodness for Google and good free math help sites. The biggest problem with this book is the lack of explanations for the practice problems which differ from the examples and are much harder. The hardest practice problems are marked with asterisks but sadly even these are not explained. This is the second Statistics course I've taken and I feel as if this book is confusing everything I learned in the first one. If this book weren't required for class I'd burn it. |
Mathematical Statistics with Applications
| Customer Rating: | | If you have to have this particular book for a class, then you have no choice. But, if you don't, this book has a lot of problems with very little help in solving them, unless you obtain a solution manual. |
Lacking in useful examples and theorems
| Customer Rating: | I had to use this text for my Stat Theory classes. This book is very frustrating in that it fails to mention some very useful theorems. Example: A problem from Ch. 3 asks: If Y is a random variable with moment-generating function m(t), and if W is given by W = aY + b, show that the m.g.f. of W is e^(tb)*m(at). In the section containing this problem, two theorems are omitted, one of which states that if X and Y are indep. random variables having m.g.f.'s Mx(t) and My(t), respectively, then Mx+y(t) = Mx(t)*My(t).
Would have been nice to know this while trying to write the proof since one might not know this theorem and assume that Mx+y(t) = Mx(t) + My(t). You run into this situation again and again in this book, whereas you can buy a Schaum's Outline of Probability and Statistics for about 1/6th the price and it has this theorem. If you need to buy this book, I recommend Schaum's which also has a lot more worked problems to study. This book is another example of old professors writing a bad text to make themselves feel smarter than students who are 30 years younger then them and can't rediscover well-known theorems in their spare time. |
A Weak Choice For Upper Division
| Customer Rating: | | The text isn't "bad," but I would look elsewhere. Sections and exercises are numbered in an uncomfortable way. Important topics and formulae are hidden within dense paragraphs, instead of being visually offset. The overall graphic and textual communication works... barely. There is much room for improvement. |
