A cusum control chart approach for screening active effects in orthogonal-saturated experiments

摘要

The analysis of designs based on saturated orthogonal arrays poses a very difficult challenge since there are no degrees of freedom left to estimate the error variance. In this paper we propose a heuristic approach for the use of cumulative sum control chart for screening active effects in orthogonal-saturated experiments. A comparative simulation study establishes the powerfulness of the proposed method.
