Hardin-Sloane Design Type
Hardin-Sloane designs, not available until 1991, can often give you better
precision of prediction in fewer runs. Hardin-Sloane designs are also known as
optimal designs: I-optimal, D-optimal, and A-optimal. They are usually based on
I-optimality and can be tailored to your specific problem, combining process,
mixture and discrete variables, and linear constraints. They typically require
20-40% fewer experiments for the quadratic model than Interaction plus Star or
Uniform Shell designs.
STRATEGY for Windows generates both Cubical and Spherical Hardin-Sloane
designs for 2-7 factors, and the software can analyze design of this type for
virtually any number of factors. To obtain a design for more factors, please call
