        Quantiles, i.e., the upper limit of integration.
    out : ndarray, optional
        Optional output array for the function results

    Returns
    -------
    nc : scalar or ndarray
        Noncentrality parameter

    See Also
    --------
    nctdtr :  CDF of the non-central `t` distribution.
    nctdtrit : Inverse CDF (iCDF) of the non-central t distribution.
    nctdtridf : Calculate degrees of freedom, given CDF and iCDF values.

    Examples
    --------
    >>> from scipy.special import nctdtr, nctdtrinc

    Compute the CDF for several values of `nc`:

    >>> nc = [0.5, 1.5, 2.5]
    >>> p = nctdtr(3, nc, 1.5)
    >>> p
    array([0.77569497, 0.45524533, 0.1668691 ])

    Compute the inverse. We recover the values of `nc`, as expected:

    >>> nctdtrinc(3, p, 1.5)
    array([0.5, 1.5, 2.5])
