Abstract:
|
Run length distribution is well recognized as a powerful measurement for the performance of a control chart. Conventionally, Average Run Length (ARL) is used as a simple criterion. However, using the average to present the entire probability distribution is not informative, and sometimes may be misleading. Continuous Ranked Probability Score (CRPS) is proposed here as a new criterion for the performance of control charts. It is shown that the newly proposed method is an ideal characteristic to present the run length distribution. Some theoretical supports are derived with examples for illustration.
