Abstract:
|
In a screening design, often only a few factors from a large number of potential factors are significantly important. The projection property is an important issue when selecting a screening design. In this talk, we shall discuss the projection properties of Hadamard designs with run-size up to 60. We are typically interested in finding Hadamard designs whose all $k-$column projections are able to entertain and estimate all 2-factor-interactions along with its main effects, assuming higher order interactions are negligible. A discussion is also made of the possible application of our finding to the robust parameter design, an important statistical tool in quality engineering with aims at reducing the variation of the system.
