Specifying axial value as rotatable in custom design
Hello,
I am trying to create a custom DOE in order to maximize the response yield of a target quantity as a function of two continuous factors and one 2nd level categorical factor. The interactions of these factors are of the third order, and I am specifying 2 center points. However, I also want to define axial values to set axial positions such that I get a rotatable surface, similar to that of a ...
