The writing of textbooks and making them freely available on the web is an idea whose time has arrived. Most college mathematics textbooks attempt to be all things to all people and, as a result, are much too big and expensive. This perhaps made some sense when these books were rather expensive to produce and distribute--but this time has passed.

"As a professional medical statistician of some 40 years standing, I can unreservedly recommend this textbook as a resource for self-education, teaching and on-the-fly illustration of specific statistical methodology in one-to-one statistical consulting. The topic area coverage is unparalleled in a single textbook, drawing in the usual suspects, but many not-so-usual: Classification trees, Neural networks, Structural equation modeling, to name but a few. This book is an absolute friend-in-need when you need to get to the point fast, without fuss, in a way that anyone can understand." — Mr. Paul W.
