LEAST SQUARES REGRESSION 1. ... Use your calculator to compute the sum of squared residuals from the regression line. The calculator automatically computes and enters the residuals into a list named RESID every time you use it to find the linear regression equation. You can use the sum (command from the LIST MATH menu and also use the key to ...

The Least Squares Regression Line. Linear regression finds the straight line, called the least squares regression line or LSRL, that best represents observations in a bivariate data set. Suppose Y is a dependent variable, and X is an independent variable. The population regression line is: Y = Β0 + Β1X

Caution: Once you do a linear regression, there is a set of residuals that are stored automatically in the list resid on your calculator. It gets replaced if you run a linear regression on another set of data. You cannot save the residual list. You must run the correct regression before getting the residual plots. 22.
