ppf

Weibull.ppf(P)

Percent Point Function (PPF) or quantile function.

The PPF for the three-parameter Weibull distribution is:

\[Q(p | k, \lambda, \gamma) = \gamma + \lambda (-\ln(1 - p))^{1/k}\]

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]
