Baxter-King Filter

The Baxter-King Filter method is applied to series values. It is included in the Smoothing group.

Baxter-King filter is a method for smoothing a time series, that is, a modification of the Hodrick-Prescott filter, but it has wider options for removing cyclic component from a time series.

To apply the method

After the method is applied, in the workbook, based on each selected series a calculated series with a name of the Baxter-King Filter (<Series_Name>) type is created, containing the calculation results. For example:

Setting Up Calculation Parameters. The Parameters Tab

To set up calculation parameters, use the Parameters side panel tab.

To display the tab

Method parameters:

Cycle Period. Determine the value of the upper and the lower limits of the cycle period.

Values of lag or lead and cycle period limits are set in accordance with calendar frequency of the series. Default values:

Frequency	Lead/Lag	Lower value	Upper value
Annual	3	2	8
Semi-annual	6	3	16
Quarterly	12	6	32
Monthly	36	18	96
Weekly	156	78	416
Daily (five days a week)	783	391,5	2088
Daily (seven days a week)	1095	547,5	2920

Lead/Lag. Determine the range, at which the moving average is calculated.
Save to Calculated Series. Select the series, which values will be contained in the output data series.
