"The great value of this book is that it presents, in an easily
understood form, the methods which will be needed in most
situations" - Journal of Epidemiology and Community Health

"...this is a superb book, full of useful information.

...The book is logically organized into 18 short, highly
readable chapters.

...as a teaching tool, it is invaluable...this book is a handy
reference to have on one's bookshelf with nearly all confidence
interval formulae organized in one place.

...In summary, Statistics with Confidence and the CIA software
are resources that every biostatistician could benefit from."
