rvgamma: Generate Random Variables from a Gamma Sampling Model

In jsta/rv: Simulation-Based Random Variable Objects

Description

Generates random variables from a Gamma sampling model.

Usage

rvgamma(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

Details

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

Value

A random vector (rv object).
