Compute the upper regularized incomplete Gamma function Q(a, x).
tf.math.igammac(
a: Annotated[Any, tf.raw_ops.Any],
x: Annotated[Any, tf.raw_ops.Any],
name=None
) -> Annotated[Any, tf.raw_ops.Any]
Used in the notebooks
The upper regularized incomplete Gamma function is defined as:
\(Q(a, x) = Gamma(a, x) / Gamma(a) = 1 - P(a, x)\)
where
\(Gamma(a, x) = \int_{x}^{\infty} t^{a-1} exp(-t) dt\)
is the upper incomplete Gamma function.
Note, above P(a, x) (Igamma) is the lower regularized complete
Gamma function.
