Review“…this is an excellent book which could easily be used as a course text…” (International Statistical Institute, January 2006)\"Twenty years after the release of the excellent previous edition, the author has succeeded in putting together a superb and inviting third edition…\" (Technometrics, August 2005) Product DescriptionMaster linear regression techniques with a new edition of a classic textReviews of the Second Edition:\"I found it enjoyable reading and so full of interesting material that even the well-informed reader will probably find something new . . . a necessity for all of those who do linear regression.\"—Technometrics, February 1987\"Overall, I feel that the book is a valuable addition to the now considerable list of texts on applied linear regression. It should be a strong contender as the leading text for a first serious course in regression analysis.\"—American Scientist, May–June 1987Applied Linear Regression, Third Edition has been thoroughly updated to help students master the theory and applications of linear regression modeling. Focusing on model building, assessing fit and reliability, and drawing conclusions, the text demonstrates how to develop estimation, confidence, and testing procedures primarily through the use of least squares regression. To facilitate quick learning, the Third Edition stresses the use of graphical methods in an effort to find appropriate models and to better understand them. In that spirit, most analyses and homework problems use graphs for the discovery of structure as well as for the summarization of results.
