# tf.math.betainc

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

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.
