As in simple linear regression, we evaluate the linearity assumption #1 by looking at the residual plot. This time we plot the residuals versus the predicted Y’s (the ’s). We can think of the ’s as summarizing all the information in the X’s.

R denotes an observation with a large standardized residual. X denotes an observation whose X value gives it large influence. Page 21. Plot of Residuals vs. Fitted Values ‘Four in One Plot’ Still some unusual observations but plots looks much better. Before leaving this example, we note the following relationship:

Normal probability plot for residuals shows more or less normality of them: The plot of residuals vs all the fitted and X1 and X2 and their product shows uniform spread, so regression function is linear in any of these: Conduct a formal test for lack of fit of the first-order regression function; use a = .01.

Explain what a residual plot in regression analysis represents conceptually (using X or predicted scores on the X-axis). Name three regression problems that a residual plot is useful for identifying and describe why it is useful for identifying each problem. Distinguish between mediation and moderation.

Residual plot (not very useful in the same way as they are in linear regression) Values above 3 of standardized residuals are cause for concern. This plot shows a curve in the top line with some values of 4 or above, likely to be corresponding to those patients with pressure ulcers who were misclassified by …
