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

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.
