RegularizedIncompleteBetaInverse

RegularizedIncompleteBetaInverse(a, b, x, tail=False)

Inverse of the regularized incomplete Beta function.

\forall (a, b) > 0, \quad
RegularizedIncompleteBetaInverse(x; a, b) = \mathrm{I}^{-1}(x; a, b)

Parameters
a, bfloat \in \Rset^*_+
xfloat
tailbool, optional

By default, tail is False.

Returns
resultfloat
  • If tail is False: result = \mathrm{I}^{-1}(x; a, b).

  • If tail is True: result = 1 - \mathrm{I}^{-1}(x; b, a).
