Simulation Study for Parametric EWMA and NPWEWPA-SR Control Charts Against Non-Normality Assumptions
Cauchy: Jurnal Matematika Murni dan Aplikasi, 2023 Common control chart types such as EWMA require assumptions to have valid information. The study compares IC robustness and OOC performance for parametric EWMA and NPEWMA-SR control charts in violation of symmetrical assumption.

EWMA Algorithm in Network Practice
International Journal of Computers Communications & Control, 2010 Intrusion detection is used to monitor and capture intrusions into computer and network systems which attempt to compromise their security. Many intrusions manifest in changes in the intensity of events occuring in computer networks. Because of the ability of exponentially weighted moving average (EWMA) control charts to monitor the rate of occurrences

A Simple Approach for Monitoring Business Service Time Variation
The Scientific World Journal, 2014 Control charts are effective tools for signal detection in both manufacturing processes and service processes. Much of the data in service industries comes from processes having nonnormal or unknown distributions.

SSRN Electronic Journal, 2021 This paper introduces the exponentially weighted moving average (EWMA) Heston model, a Markovian stochastic volatility model able to capture a wide range of empirical features related to volatility dynamics while being more tractable for simulations than rough volatility models based on fractional processes. After presenting the model and its principal
