Simple Linear Regression Case. As briefly discussed in the previous reading assignment, the most commonly used estimation procedure is the minimization of the sum of squared deviations. This procedure is known as the ordinary least squares (OLS) estimator. In this chapter, this estimator is derived for the simple linear case.

The smallest percentage of bad data that can cause the fitted line to explode is defined as the breakdown point. Since a single bad data point can destroy the least squares line, LS is said to have a zero breakdown point. Thus, least squares is not a robust regression procedure.

Defn: Least Squares Method of Estimation = estimate the regression line (slope and intercept) so that the squared vertical distances are minimized. The line that does this is the Least Squares Line. Least Squares Line = line that minimizes squared vertical distances of points to the line EXAMPLE: Snake Data. Goal: Find the line that minimizes ...

Answer: Method of Least Squares. To fit the model we first select . Analyze > Fit Y by X. and place Systolic BP in the Y box and Diastolic BP in the X box as shown below. This will give us scatter plot of Y vs. X, from which we can fit the simple linear regression model. The resulting scatter plot is shown below. With regression line added.

This line is called the (least-squares) regression line of y on x (because the equation has been given with y the subject). b is sometimes called the regression coefficient of y on x. We can work out the equation for our example as follows: So, and . So the equation of the regression line is y …
