ppf

Normal.ppf(P)

Percent Point Function (PPF) or quantile function.

The PPF is the inverse of the Cumulative Distribution Function (CDF). This implementation relies on scipy.stats.norm.ppf for accuracy and robustness.

Parameters:

P (ArrayLike) – The probability values (between 0 and 1) at which to evaluate the PPF.

Returns:

The PPF values corresponding to each probability in P.

Return type:

NDArray[np.float64]
