CHAPTER 3

Illustration of Least Squares Regression Method

In this chapter we provide a complete analysis of simple regression model. The least squares method that is the basis of regression model is used to estimate the best-fitting regression line. We will discuss the process of finding the regression equation, and calculate and interpret several measures to assess the quality of the regression model. The analysis in this chapter will help us understand and interpret the computer results in the subsequent chapters.
