 {{alias}}( [out,] window )
-    Returns an accumulator function which incrementally computes a moving range.

     The `window` parameter defines the number of values over which to compute

-    The first `W-1` returned ranges will have less statistical support than
-    subsequent ranges, as `W` values are needed to fill the window buffer. Until
