tf.math.betainc

TensorFlow 2.0 version

Defined in generated file: python/ops/gen_math_ops.py

Compute the regularized incomplete beta integral \(I_x(a, b)\).

Aliases:

  • tf.betainc
  • tf.compat.v1.betainc
  • tf.compat.v1.math.betainc
  • tf.compat.v2.math.betainc
tf.math.betainc(
    a,
    b,
    x,
    name=None
)

The regularized incomplete beta integral is defined as:

\(I_x(a, b) = \frac{B(x; a, b)}{B(a, b)}\)

where

\(B(x; a, b) = \int_0^x t^{a-1} (1 - t)^{b-1} dt\)

is the incomplete beta function and \(B(a, b)\) is the complete beta function.

Args:

  • a: A Tensor. Must be one of the following types: float32, float64.
  • b: A Tensor. Must have the same type as a.
  • x: A Tensor. Must have the same type as a.
  • name: A name for the operation (optional).

Returns:

A Tensor. Has the same type as a.
