# scipy.special.fdtrc

scipy.special.fdtrc(dfn, dfd, x) = <ufunc 'fdtrc'>

  F survival function.

  Returns the complemented F-distribution function (the integral of the density from x to infinity).

  Parameters
    dfn array_like

      First parameter (positive float).

    dfd array_like

      Second parameter (positive float).

    x array_like

      Argument (nonnegative float).

  Returns
    y ndarray

      The complemented F-distribution function with parameters dfn and dfd at x.

  Notes

  The regularized incomplete beta function is used, according to the formula,

  \[F(d_n, d_d; x) = I_{d_d/(d_d + xd_n)}(d_d/2, d_n/2).\]

  Wrapper for the Cephes [1] routine `fdtrc`.
