About This Book
Providing a self-contained exposition of the theory of linear models, this treatise strikes a compromise between theory and practice, providing a sound theoretical basis while putting the theory to work in important cases.

CHAPTER 1
Simple Linear Regression
Linear models are used for studying the explanation of a given variable in terms of a linear combination of given explanatory variables. In the present chapter, we discuss the case of one explanatory variable, as a preparation for the general case, which is treated in Chapter 2 and onwards. Readers already familiar with simple linear regression may want to go directly to Chapter 2, with occasional reference to Chapter 1 as necessary.
1.1 The linear regression model
Consider an experiment in which we make simultaneous measurements of two variables x and y for a range of different experimental conditions. If we make n measurements, let
denote the corresponding n pairs of observations. We construct a statistical model for the situation where the relationship between x and y is thought to be linear or approximately so.
Often x represents the experimental conditions, and y represents the outcome of the experiment. The variable y is called the response variable or the dependent variable. We assume that y1, …, yn are realizations of independent random variables Y1, …, Yn. In contrast, the values xl, …, xn are considered constant (non-random), and x is called the explanatory variable or the independent variable. We must hence make a clear distinction between the response and explanatory varia...
