Multiple regression in practice

The authors provide a systematic treatment of many of the major problems encountered in using regression analysis. Because it is likely that one or more of the assumptions of the regression model will be violated in a specific empirical analysis, the ability to know when problems exist and to take appropriate action helps to ensure the proper use of the procedure. Responding to this need, the authors clearly and concisely discuss the consequences of violating the assumptions of the regression model, procedures for detecting when such violations exist, and strategies for dealing with these problems when they arise.
