# weighted moving average method forecasting

The Weighted Moving Average method is usually used for smoothing purposes. However, it can be used to forecast Y(t1) based on the last n observed data. In real-world problems, forecasting in very short horizon (h 1) is not very interesting. This type of forecasting is called weighted moving average. Here we assign m weights w1, , wm, where w1 . wm 1, and define the forecasted values as follows. In the simple moving average method all the weights are equal to 1/m. What is Weighted Moving Average Method? This approach is based on the principle that more weightage should be given to relatively newer data. The forecast is the weighted average of data.
