On Factorial Effects Corresponding to Orthogonal Arrays with Unequal Strength
Search this Article
Orthogonal Arrays (OAs) have been playing important roles in the field of experimental design. It is well known that OAs are closely related to error-correcting codes, and many good OAs are constructed from error-correcting codes. And factorial effects that can be estimated with OAs corresponding to error-correcting codes are clarified. On the other hand, in our past researches, we focused on the relation between OAs and unequal error protection codes (UEP codes). OAs corresponding to UEP codes are called OAs with unequal strength (UOAs), where OAs corresponding to error-correcting codes are called OAs with equal strength. We showed that UOAs are more practical than OAs with equal strength, and proposed some construction methods of UOAs from UEP codes. But, in the researches, we only showed some examples of factorial effects that can be estimated with UOAs, so we had never clarified these factorial effects as well as OAs with equal strength. In this paper, we clarify factorial effects that can be estimated with UOAs.
