How DoE model evaluation impact final model after experiment?
Hi Folks, I have several questions about DoE, could you please answer them? Thank you so much. 1) Due to experiment constraint, can I manually adjust center point value for example (-1)= 10, (+1)= 12, (0) = 11. But (0) = 11 is not a good center point, can I change to 10.5 in the design? How this change will impact the data analysis and final model as well as model prediction? what if I used (0)= 1...
