Model initialization is the process of determining the necessary model parameters ¾ such as the basic value, the trend value, and the seasonal indices ¾ for the selected forecast model. Initialization takes place each time a planning time series is forecasted.

As a general rule, the forecast model is initialized automatically. In order to do this, the system requires a certain number of historical values. This number depends on the forecast model,like

Constant model -1

Trend model -3

Seasonal model- 1 season

Seasonal trend model: 1 season + 3

2nd-order exponential smoothing: 3

Moving average: 1

Weighted moving average 1
