Brown’s Weighted Exponential Moving Average Implementation in Forex Forecasting [PDF]
TELKOMNIKA (Telecommunication Computing Electronics and Control), 2017 In 2016, a time series forecasting technique which combined the weighting factor calculation formula found in weighted moving average with Brown’s double exponential smoothing procedures had been introduced. The technique is known as Brown’s weighted exponential moving average (B-WEMA), as a new variant of double exponential smoothing method which does

The exponentiated exponentially weighted moving average control chart
Statistical PapersAbstractMemory-type control charts are widely used for monitoring small to moderate shifts in the process parameter(s). In the present article, we present an exponentiated exponentially weighted moving average (Exp-EWMA) control chart that weights the past observations of a process using an exponentiated function.

ON PERFORMANCE OF METHODS FOR STATISTICAL SURVEILLANCE [PDF]
, 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.
