Praise for Larry Hatcher

The problems are interesting, and the tasks required are those a
researcher must undertake. Students who work through all of the
exercises in this book will definitely be confident and prepared to
use SAS to conduct these analyses independently.

My graduate students and I have had a good chance to look over
the new workbook...The general consensus is that it is extremely
successful on a number of levels. [Larry Hatcher has] thought of
everything...We especially like how [he] incorporated additional
explanations to help students navigate the computer itself.
