Time Series Forecast Using Moving Average and Exponential Smoothing …
Webα = smoothing factor of data; 0 < α < 1. t = time period. b t = best estimate of trend at time t. β = trend smoothing factor; 0 < β <1. Triple exponential smoothing. In this method, exponential smoothing applied three times. This method is used for forecasting the time series when the data has both linear trend and seasonal pattern. WebThe average needs to be calculated for each three-month period. To do this you move your average calculation down one month, so the next calculation will involve February, March and April. The total for these three months would be (145+186+131) = 462 and the average would be (462 ÷ 3) = 154. bosmans tractoren
