Custom Design - I-optimal - center points not added

Nov 18, 2016 07:17 AM (18824 views)

Hi All,

I just tried to design an I-optimal Experiment with 7 continuous factors with 48 runs. Within I'd like to have 6 center points. However, JMP does simply not include those, despite me entering those explicitly in the "Number of Center Point" field.

Any ideas?

Thanks!

Hi Dave,

so you got 6 center points?

That eventually means I am doing something different, doesn't it? Since it is not a complicated thing to make this design, I wonder what I am doing worng - any comments appreciated!

Concerning the manual addition of center runs: Thanks for your explanations!

Yeah that's weird.  If you want I can make a video then you can do a comparison.  What version of JMP are you using?
