{{alias}}()
    Returns an accumulator function which incrementally computes the residual
    sum of squares (RSS), ignoring `NaN` values.

    If provided input values, the accumulator function returns an updated
    residual sum of squares. If not provided input values, the accumulator
    function returns the current residual sum of squares.

    NaN input values are ignored.
