rv (version 2.0.0)

rvgamma: Generate Random Variables from a Gamma Sampling Model

Description

Generates random variables from a Gamma sampling model.

Usage

rvgamma(n=1, shape, rate = 1, scale = 1/rate)
  rvngamma(n=1, shape, rate = 1, scale = 1/rate)

Arguments

n

integer: number of variables to generate

shape

shape parameter, may be a rv

rate

rate parameter, may be a rv

scale

inverse of rate, may be specified optionally instead of rate

Value

• A random vector (rv object).

Details

rvngamma(n, shape, rate) is equivalent to rvgamma(n, 1/3 + shape, rate).
