def _ecdf_formal(x, data):

    Compute the values of the formal ECDF generated from `data` at x.

    Parameters
    ----------
    x : array_like
        Positions at which the formal ECDF is to be evaluated.
    data : array_like
        *Sorted* data set to use to generate the ECDF.

    -------
    output : float or ndarray
        Value of the ECDF at `x`.
