Struct yata::methods::SWMA

pub struct SWMA(_);

Symmetrically Weighted Moving Average of specified length for timeseries of ValueType.

F.e. if length = 4, then weights are: [ 1.0, 2.0, 2.0, 1.0 ].

If length = 5, then weights are: [ 1.0, 2.0, 3.0, 2.0, 1.0 ].

Parameters

Has a single parameter length: PeriodType

length should be > 0

Input type

Input type is ValueType

Output type

Output type is ValueType

Perfomance

O(length)

This method is relatively slower compare to the most of the other methods.
