A Multivariate Homogeneously Weighted Moving Average Control Chart
IEEE Access, 2019 This paper presents a multivariate homogeneously weighted moving average (MHWMA) control chart for monitoring a process mean vector. The MHWMA control chart statistic gives a specific weight to the current observation, and the remaining weight is evenly ...

Multivariate Control Chart based on Neutrosophic Hotelling T2 Statistics and Its Application
JTAM (Jurnal Teori dan Aplikasi Matematika), 2022 Under classical statistics Hotelling 〖 T〗^2 control chart is applied when the observations of quality characteristics are precise, exact, or crips data. However, in reality, under uncertain conditions, the observations are not necessarily precise, exact,

Self‐adapting control charts [PDF]
Statistica 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.

Design of a Control Chart Using Extended EWMA Statistic
Technologies, 2018 In the present paper, we propose a control chart based on extended exponentially weighted moving average (EEWMA) statistic to detect a quick shift in the mean. The mean and variance expression of the proposed EEWMA statistic are derived.
