hyperexponential_distribution: Hyperexponential Distribution Functions

Description

Functions to compute the probability density function, cumulative distribution function, and quantile function for the Hyperexponential distribution.

Usage

hyperexponential_pdf(x, probabilities, rates)
hyperexponential_lpdf(x, probabilities, rates)
hyperexponential_cdf(x, probabilities, rates)
hyperexponential_lcdf(x, probabilities, rates)
hyperexponential_quantile(p, probabilities, rates)

Value

A single numeric value with the computed probability density, log-probability density, cumulative distribution, log-cumulative distribution, or quantile depending on the function called.

Arguments

x

quantile

probabilities

vector of probabilities (sum must be 1)

rates

vector of rates (all rates must be > 0)

p

probability (0 <= p <= 1)
