Parameters specifying the design |
This function uses stage_two to find optimal stage-two functions and optimizes then over the stage one parameters n1, cf and ce. It is a more suitable way than the one that is used in direct_design because one only evaluates the stage two-functions inside the interval (cf,ce) and not on a full grid. This function yields smoother results than direct_design, but also takes more time.
An object of class design.
