Hello,
I am now following the practice in a textbook but I cannot mimic the auther's work.
The book is Douglas C. Montgomery, Design and analysis of experiments (2020)
On page 445 ~ 448, Example 11.3, summary is as follow.
4 factors,
in exact 16 runs,
D-optimal
Using JMP
The result is,
However, I cannot mimic this result since,
JMP>Custom DOE>
- 4 Continuous factors
- RSM
- 'D-optimality'
- runs: 16
above 4 are my designated values, as per following figure
However, the result is not same to the textbook.
It always includes below decimal Level of the factor(s)., as follows.
Thus there is no identity between the textbook.
What point did I miss?
Please tell me how to get through.
