Use Stat > Regression > Regression to find the regression equation AND make a residual plot of the residuals versus the explanatory variable. To make the residual plot, use “Graphs” and then type in the name of the explanatory variable. At home: Read Chapter 5 and work the problems at the end of each short section as you go through them.

Prerequisites for Regression. Simple linear regression is appropriate when the following conditions are satisfied. The dependent variable Y has a linear relationship to the independent variable X. To check this, make sure that the XY scatterplot is linear and that the residual plot shows a random pattern.

The students are then asked to use a computer or graphical calculator to carry out the linear regression of BAC on number of beers. The students are asked to interpret almost every number that the computer output gives. The students are then asked to make a residual plot and judge the appropriateness of the linear regression line.

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.

A residual plot for a set of data with a linear regression equation is shown. Which statement is correct? The least squares regression line is a good fit since there is a definite pattern in the residual plot.

Use the regression line to compute the fitted value and residual for a baboon. (Note: You can look at the table of values to find the fitted value and residuals are automatically calculated by the calculator and stored in a list called Residuals.)

We now examine the output, including findings with regard to multicollinearity, whether the model should be trimmed (i.e., removing insignificant predictors), violation of homogeneity of variance and normality assumptions, and outliers and influential cases.
