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
- dfnarray_like
First parameter (positive float).
- dfdarray_like
Second parameter (positive float).
- xarray_like
Argument (nonnegative float).
- Returns
- yndarray
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
