Question:
Now restrict the data set in Exercise 11.15 to eight, then six, then five cases, and record the changing values of R. Remember that these are only random data.
Exercise 11.15
Use the table of random numbers (Table E.9 in the Appendix) to generate data for 10 cases on six variables, and label the first variable Y and the following variables X1, X2, X3, X4, and X5.
Now use any regression program to predict Y from all five predictors using the complete data set with 10 cases. Are you surprised at the magnitude of R?
