Simulated Responses

Simulated Responses - Experimental designs are sometimes applied to deterministic systems, such as electronic hardware, with many operating and environmental factors or controls. It may be feasible to test all possible combinations (a complete factorial design), so a subset of all combinations (a fractional factorial) may be used to get a reasonable level of information. If there are no extrinsic sources of variation, the system will deliver an identical response each time it is exercised with a specific set of factor-levels. In such a case, where the response is completely and uniquely determined by the input factors, run randomization, repeated measurements, repeated runs and replicates have no purpose.
