{{alias}}()
    Returns an accumulator function which incrementally computes a corrected
    sample excess kurtosis.

    If provided a value, the accumulator function returns an updated corrected
    sample excess kurtosis. If not provided a value, the accumulator function
    returns the current corrected sample excess kurtosis.

    If provided `NaN` or a value which, when used in computations, results in
    `NaN`, the accumulated value is `NaN` for all future invocations.

    Returns
    -------
    acc: Function
        Accumulator function.

    Examples
    --------
    > var accumulator = {{alias}}();
    > var v = accumulator( 2.0 )
    null
    > v = accumulator( 2.0 )
    null
    > v = accumulator( -4.0 )
    null
    > v = accumulator( -4.0 )
    -6.0
