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(dn,dd;x)=Idd/(dd+xdn)(dd/2,dn/2).

Wrapper for the Cephes [R358] routine fdtrc.
