Weighted Moving Average

This applies to: Managed Dashboards, Managed Reports

The Weighted Moving Average (WMA) function computes the average of a set of input values over a specified number of time periods. In this function, a greater weight is given to more recent data. The function can be used to smooth a data series, which helps to reduce noise and make it easier to spot data trends.

The mathematical formula being calculated is as follows:

Where Y is the value, n is the number of periods, and K is the sum of n-based multipliers (for example, for n=3, K=3+2+1 =6).

Syntax

WGHTMOVAVG(d0,s0,Alignment)

Input

The Weighted Moving Average function requires the following input:

• d0 - Input data values - The set of data values for which the Weighted Moving Average is calculated.

Parameters

The Weighted Moving Average function requires the following parameters:

• s0 Period - The number of time periods to use in the calculation. The default value is 10.

• Alignment (Optional) - Hierarchy placeholder to be used as the alignment axis.

Output

The Weighted Moving Average function generates the following output:

• Weighted Moving Average - The Weighted Moving Average result set.
