Overview for Decomposition

Use Decomposition to separate a time series into linear trend, seasonal, and error components, and to provide forecasts. You can choose whether the seasonal component is additive or multiplicative with the trend. Use this analysis to generate forecasts and assess the components when your series has a seasonal component.

For example, a marketing analyst wants to predict sales of a golf driver. The analyst collects previous sales data to predict the sales of the product for the next six months.
