Regression is a popular research area, and regression analysis is an ever-changing collection of techniques. This book offers a synthesis of state-of-the-art regression methodology. Featuring a strong data analysis orientation, it presents regression diagnostics in a uniquely comprehensive manner. Each chapter contains a brief section for SAS, Minitab, SPSS, BMDP, and Systat users, though particular software packages are not emphasized overall. Enhancements to the second edition include a unification and expansion of subject areas addressed in the first edition, as well as an increased emphasis on applications. Modern Regression Methods offers a peerless resource for students, researchers, and practitioners alike.
