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.

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

Analysis of Moving Average, Weight Moving Average, Exponential Smoothing in predicting shoe prices
Jurnal Teknologi Informasi dan Pendidikan, 2022 Research related to forecasting is growing, starting with simple forecasting based on time or forecasting with certain criteria. Forecasting methods continue to be developed because they produce good models and can predict with high accuracy. The simplest method of forecasting is from the statistical value of the data, namely the average value or what ...
