The General Linear Model

Introduces the General Linear Model and the methods that can be derived from it, including direction dependence analysis.

von Eye and Wiedermann present the General Linear Model (GLM) and derivatives such as correlation, regression, analysis of variance, and direction dependence analysis in a compact format. Each method is illustrated using real-world data so that students, instructors, and data analysts can understand methods and procedures.General Linear Model methods are the most widely used in data analysis in applied empirical research. Still, there exists no compact text that can be used in statistics courses and as a guide in data analysis. This volume fills this void by introducing the General Linear Model (GLM), whose basic concept is that an observed variable can be explained from weighted independent variables plus an additive error term that reflects imperfections of the model and measurement error. It also covers multivariate regression, analysis of variance, analysis under consideration of covariates, variable selection methods, symmetric regression, and the recently developed methods of recursive partitioning and direction dependence analysis. Each method is formally derived and embedded in the GLM, and characteristics of these methods are highlighted. Real-world data examples illustrate the application of each of these methods, and it is shown how results can be interpreted.
