Regression and ANOVA: An Integrated Approach Using SAS Software
The book contains a balanced treatment of regression and ANOVA yet is very compact. Reflecting current computational practice, most sums of squares formulas and associated theory, especially in ANOVA, are not included. The text contains almost no proofs, despite the presence of a large number of basic theoretical results. Many numerical examples are provided, and include both the SAS code and equivalent mathematical representation needed to produce the outputs that are presented.
All exercises involve only "real" data, collected in the course of scientific research. The book is divided into sections covering the following topics:
* Basic Theory
* Multiple Regression
* Model Building and Evaluation
Examples and Limits of the GLM.
Statement of the Model, Estimation, and Testing.
Some Distributions for the GLM.
Multiple Regression: General Considerations.
Testing Hypotheses in Multiple Regression.
GLM Assumption Diagnostics.
GLM Computation Diagnostics.
Selecting the Best Model.
Coding Schemes for Regression.
Complete, Two-Way Factorial ANOVA.
Special Cases of Two-Way ANOVA and Random Effects Basics.
The Full Model in Every Cell (ANCOVA as a Special Case).
Understanding and Computing Power for the GLM.
