{{alias}}( W )
Returns an accumulator function which incrementally computes a moving sum of
squared absolute values.
The `W` parameter defines the number of values over which to compute the
moving sum.
If provided a value, the accumulator function returns an updated moving sum.
If not provided a value, the accumulator function returns the current moving
sum.
As `W` values are needed to fill the window buffer, the first `W-1` returned
values are calculated from smaller sample sizes. Until the window is full,
each returned value is calculated from all provided values.
Parameters
----------
W: integer
Window size.
Returns
-------
acc: Function
Accumulator function.
Examples
--------
> var accumulator = {{alias}}( 3 );
> var s = accumulator()
null
> s = accumulator( 2.0 )
4.0
> s = accumulator( -5.0 )
29.0
> s = accumulator( 3.0 )
38.0
> s = accumulator( -5.0 )
59.0
> s = accumulator()
59.0
