Cusum charts for preliminary analysis of individual observations

A preliminary Cusum chart based on individual observations is developed from the uniformly most powerful test for the detection of linear trends. This Cusum chart is compared with several of its competitors which are based on the likelihood ratio test ...

ON PERFORMANCE OF METHODS FOR STATISTICAL SURVEILLANCE

, 1994
Statistical surveillance is used to detect a change in a process. It might for example be a change of the level of a characteristic of an economic time series or a change of heart rate in intensive care.

The upward CUSUM chart.

, 2014
The CUSUM curve tended to be flat until the 25th case. After the initial 25 cases, the curve showed a rising pattern but declined again. However, CUSUM curve showed an upward shift. After the 56th case, the change point analysis result presented the 56th

Performance Evaluation of Shiryaev–Roberts and Cumulative Sum Schemes for Monitoring Shape and Scale Parameters in Gamma-Distributed Data Under Type I Censoring

Axioms
This paper proposes two process monitoring schemes, namely the Shiryaev–Roberts (SR) procedure and the cumulative sum (CUSUM) procedure, to detect shifts in the shape and scale parameters of Type I right-censored Gamma-distributed lifetime data.

An introduction to the Bernoulli CUSUM

2017 Annual Reliability and Maintainability Symposium (RAMS), 2017
The Bernoulli CUSUM (BC) provides a moving window of process performance and is the quickest control chart to detect small increases in fraction defective. The Bernoulli CUSUM designs presented here require 2, 3, or 4 failures in a moving window to produce a signal.

Cumulative Summation (CUSUM)—as a tool for objective analysis of learning curve for surgeons in acquiring competency in phacoemulsification

BMC Ophthalmology
Background Phacoemulsification is the most widely performed cataract surgery and a key indicator of surgical competency for ophthalmologists. This study applies cumulative summation (CUSUM) analysis to a large national dataset to identify the number of ...
