How to determine term significance based on power value?
Using the design evaluation tool in JMP, I compared a Box-Behnken design with a Custom design (with 28 runs) to evaluate 5 factors with 3 levels each (see below):Given the comparison, the custom design was chosen for the experimental runs. In the evaluation, I found the quadratic terms to be statistically significant (p<0.05) for one or more responses, despite the power for these terms being low a...
