    Parameters
    ----------
    bucket_size (float)
        The size of each bucket, in percentile points 0-100. Actual bucket
        cutoffs are calculated with numpy.arange(), so if 100 isn't divisible
        by bucket_size, your top bucket will be small.
    scale (float)
        All values will be multiplied by this number after bucketing.
    shift (float)
        All values will have this added to them after scaling.
