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.
