In Exhibit 3.10, what makes the residuals standardized? Because the standardized residuals vary from -10 to 10 implies that they did not necessarily standardize them as they did in Exhibit 3.11.

Also, in Exhibit 3.12, for a Q-Q graph, how do you come up with the y-value of each data point? How do you choose the quantile marks and why do some data points exceed the -2 and 2 quartile mark?

Thanks a lot!

[NEAS: The Fox text has a clearer explanation of Q-Q plots. Read module 4 of the regression analysis course. The discussion forum postings show several Q-Q plots for different distributions.]

I agree with you on exhibit 3.10.  Indeed a brief MS Excel chart of the data shows that the values graphed are the residuals versus the fitted values.  Attachted are my findings.

No idea what this means, so you can't see my Excel spreadsheet.
