Below is the JMP data table:
We proceed as follows:
Compare these coefficients with those on Page 144 of your textbook.
We now try to reproduce Figure 5-10 on Page 146 of your textbook. We don't completely succeed but we come close. Proceed as follows:
The action above adds a column to the data table with the prediction formula:
We continue in our effort to reproduce Figure 5-10 on Page 146 of your textbook:
These actions result in the dark line on Figure 5-10:
Compare these equations with the equations on Page 145 of your textbook.
We proceed to get Figure 5-11 on Page 147 of your textbook. Proceed as follows:
Compare the equations above with the ones on Page 147 of your textbook.
