Weibull

class Weibull(shape, loc, scale)

Bases: ContinuousDistribution

Class for the three-parameter Weibull distribution.

Parameters:

• shape (float) – Shape parameter (k). Must be positive.

• loc (float) – Location parameter (gamma). Can be any real number.

• scale (float) – Scale parameter (lambda). Must be positive.

Variables:

• shape (float) – Shape parameter.

• loc (float) – Location parameter.

• scale (float) – Scale parameter.

Methods

ppf(P)	Percent Point Function (PPF) or quantile function.
pdf(X)	Probability density function (PDF).
lpdf(X)	Log of the Probability Density Function (LPDF).
log_gradients(X)	Calculates the gradients of the log-PDF w.r.t.
generate(size)	Generates random samples from the distribution.
