Efficient Homogeneously Weighted Moving Average Chart for Monitoring Process Mean Using an Auxiliary Variable

open access: yesIEEE Access, 2019
In this paper, we propose an efficient control chart for monitoring small shifts in a process mean for scenarios where the process variable is observed with a correlated auxiliary variable.

New extended exponentially weighted moving average control chart for monitoring process mean

open access: yesHeliyon
In this article, we develop a new control chart based on the Exponentially Weighted Moving Average (EWMA) statistic, termed the New Extended Exponentially Weighted Moving Average (NEEWMA) statistic, designed to recognize slight changes in the process ...

How useful are historical data for forecasting the long-run equity return distribution? [PDF]

open access: yes
We provide an approach to forecasting the long-run (unconditional) distribution of equity returns making optimal use of historical data in the presence of structural breaks. Our focus is on learning about breaks in real time and assessing their impact on

An Examination of the Robustness to Non Normality of the EWMA Control Charts for the Dispersion [PDF]

open access: yes
The EWMA control chart is used to detect small shifts in a process. It has been shown that, for certain values of the smoothing parameter, the EWMA chart for the mean is robust to non normality.

Laboratory design-studies of the effect of waves on a proposed island site for a combined nuclear power and desalting plant [PDF]

open access: yes, 1966
There were four major objectives to this investigation: 1) the determination of the degree of stability of the island face when constructed of armor units of various weights; 2) the run-up for a two-dimensional wave system impinging on the island face; 3)

Empirical Bayes Prediction for an Attribute Control Chart in Quality Monitoring

open access: yesIEEE Access
A control chart is a valuable statistical tool used in production process control to ensure that products meet quality standards. The c-chart, a specific type of control chart, monitors the number of nonconformities or defects in a production process ...
