Time series smoothing methods
WebExponential Smoothing is a technique for smoothing univariate time-series by assigning exponentially decreasing weights to data over a time period. Mathematically, the value of variable at time ‘t+1’ given value at time t, y_ (t+1 t) is defined as −. y 1,...., y t are previous values of network traffic at times 1, 2, 3, …. WebJan 1, 2016 · Smoothing methods are frequently used in time series analysis. In particular, exponential smoothing is widely used for producing short-term forecasts of many types of industrial time series. Much of the original work in this area is by Brown ( 1962 ), Holt ( 1957 ), and Winters ( 1960 ).
