## Time Series Filter Bean

The AbleTimeSeriesFilterBean bean provides a way to accumulate several periods of data into a single output. It can also 'look ahead' to obtain a target value from a data source several periods from the current input. It is particularly useful in forecasting.

The Window value specifies the number of periods to accumulate. The Horizon value provides the number of periods from the last record in the window from which to forecast the future value.
