Computes the inverse CCDF of the standard normal distribution \(\mathcal{N}(0, 1)\).

The inverse complementary cumulative distribution function (CCDF) \(Q^{-1}(p)\) is the value that is exceeded with a given probability.

Parameters:¶

p: ArrayLike¶

The probability \(p\) of exceeding the returned value \(x\).

Returns:¶

The real-valued \(x\) that is exceeded with probability \(p\).
