A study of the average run length characteristics of the National Notifiable Diseases Surveillance System

open access: yesStatistics in Medicine, 1999
This study examines the statistical properties (that is, false positive and negative signals) in detecting unusual patterns of reported cases of diseases from the Centers for Disease Control and Prevention's National Notifiable Diseases Surveillance System.

Optimal exponentially weighted moving average charts with estimated parameters based on median run length and expected median run length

International Journal of Production Research, 2016
This paper examines the exponentially weighted moving average (EWMA) chart with estimated process parameters. As the run length distribution is skewed when the process is in-control or slightly out-of-control, the average run length (ARL) provides less meaningful interpretation of a chart’s performance.

A note on an average run length calculation for the EWMA and other charts

Quality and Reliability Engineering International, 2022
AbstractIn the last decade numerous papers have appeared in the statistical process monitoring literature where the in‐control and out‐of‐control average run length (ARL) profiles of the exponentially weighted moving average chart, and some of its variants, have been approximated under the assumption that the signal event can be represented by a ...

The computation of average run length and average time to signal: an overview

Journal of Statistical Computation and Simulation, 2013
Control charts are widely used in industries to monitor a process for quality improvement. Evaluation of the average run length (ARL) or average time to signal (ATS) plays an important role in the design of control charts and performance comparison. In this paper, we review several basic and popular procedures, including the Markov chain and integral ...
