SpecFunc_RegularizedIncompleteGammaInverse¶

SpecFunc_RegularizedIncompleteGammaInverse(a, x, tail=False)¶

Inverse of the regularized incomplete Gamma function.

$\forall x \in \Rset, \quad RegularizedIncompleteGammaInverse(a, x) = \mathrm{P}^{-1}(a, x)$

Parameters:	a : float $\in \Rset^_+$ x : float $\in [0, 1]$ tail* : bool, optional By default, tail is False.
Returns:	result : float If tail is False: $result = \mathrm{P}^{-1}(a, x)$ . If tail is True: $result = \mathrm{P}^{-1}(a, 1-x)$ .
