# Practical Regression and Anova using R

## Julian J. Faraway

This book is not introductory. It presumes some knowledge of basic statistical theory and practice. Students are expected to know the essentials of statistical

inference like estimation, hypothesis testing and conﬁdence intervals. A basic knowledge of data analysis is presumed. Some linear algebra and calculus is also required.

The emphasis of this text is on the practice of regression and analysis of variance. The objective is to learn what methods are available and more importantly, when they should be applied. Many examples are presented to clarify the use of the techniques and to demonstrate what conclusions can be made. There is relatively less emphasis on mathematical theory, partly because some prior knowledge is assumed and partly because the issues are better tackled elsewhere. Theory is important because it guides the approach we take. I take a wider view of statistical theory. It is not just the formal theorems. Qualitative statistical concepts are just as important in Statistics because these enable us to actually do it rather than just talk about it. These qualitative principles are harder to learn because they are difﬁcult to state precisely but they guide the successful experienced Statistician.
