Central Composite Response Surface Method

This example validates the calculation of the central composite response surface method.

Data is from Example 11-1 on page 431 in the book “Design and Analysis of Experiments” by Douglas C. Montgomery, John Wiley & Sons, 2001.

From the book, the ANOVA table is:

The final equation in terms of actual values of these two factors is:

\[Yield= -1430.52285+7.80749×time+13.27053×temp-0.05505×〖time〗^2-0.04005×〖temp〗^2+0.01×time×temp\] .
