Cumulative Sum Charts and Charting for Quality Improvement Summary

Cumulative Sum Charts and Charting for Quality Improvement by Douglas M. Hawkins

Covering CUSUMs from an application-oriented viewpoint, while also providing the essential theoretical underpinning, this is an accessible guide for anyone with a basic statistical training. The text is aimed at quality practitioners, teachers and students of quality methodologies, and people interested in analysis of time-ordered data. Further support is available from a Web site containing CUSUM software and data sets.
