Trend control charts for multiple sclerosis case definitions [PDF]

open access: yesInternational Journal of Population Data Science
Introduction The validity of chronic disease case definitions for administrative health data may change over time due to changes in data quality. Trend control charts to identify out-of-control (OOC; i.e., unexpected) observations in a time series may ...

Comparing the efficacy of coefficient of variation control charts using generalized multiple dependent state sampling with various run-rule control charts [PDF]

open access: yesScientific Reports
This paper aimed to develop a coefficient of variation (CV) control chart utilizing the generalized multiple dependent state (GMDS) sampling approach for CV monitoring. We conducted a comprehensive examination of this designed control chart in comparison

Pearson and Deviance Residual-Based Control Charts for the Inverse Gaussian Ridge Regression Process: Simulation and an Application to Air Quality Monitoring [PDF]

open access: goldAxioms
In manufacturing and service industries, monitoring processes with correlated input variables and inverse Gaussian (IG)-distributed quality characteristics is challenging due to the limitations of maximum likelihood estimator (MLE)-based control charts ...

Self‐adapting control charts [PDF]

open access: yesStatistica Neerlandica, 2006
When the distributional form of the observations differs from normality, standard control charts are often prone to serious errors. Such model errors can be avoided by using (modified) nonparametric control charts. Unfortunately, these control charts suffer from large stochastic errors caused by estimation.

CONTROL CHARTS MONITORING FOR QUALITY CONCRETE PAVEMENTS [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2020
In this article, Control charts are employed to analyse the strength quality control of ready-mixed concrete for rigid pavement. The results of the study support that CUSUM statistical analysis is more sensitive than the Shewhart control chart. The CUSUM

Synthetic-type control charts for time-between-events monitoring. [PDF]

open access: yesPLoS ONE, 2013
This paper proposes three synthetic-type control charts to monitor the mean time-between-events of a homogenous Poisson process. The first proposed chart combines an Erlang (cumulative time between events, Tr ) chart and a conforming run length (CRL ...
