tensorflow::ops::Igammac

#include <math_ops.h>

Compute the upper regularized incomplete Gamma function Q(a, x).

Summary

The upper regularized incomplete Gamma function is defined as:

\(Q(a, x) = Gamma(a, x) / Gamma(a) = 1 - P(a, x)\)

where

\(Gamma(a, x) = int_{x}^{} t^{a-1} exp(-t) dt\)

is the upper incomplete Gama function.

Note, above P(a, x) (Igamma) is the lower regularized complete Gamma function.
