Exponential

class Exponential(loc, rate)

Bases: ContinuousDistribution

Class for the two-parameter exponential distribution.

Parameters:

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

• rate (float) – Rate parameter (lambda). Must be positive.

Variables:

• loc (float) – Location parameter.

• rate (float) – Rate 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.
