Random variate generation for micobin (mixture of continuous binomial) distribution

Description

Micobin distribution with natural parameter \theta and dispersion psi, denoted as micobin(\theta, \psi), is defined as a dispersion mixture of cobin:

Y \sim micobin(\theta, \psi) \iff Y | \lambda \sim cobin(\theta, \lambda^{-1}), (\lambda-1) \sim negbin(2, \psi)

Usage

rmicobin(n, theta, psi, r = 2)

Arguments

n	integer, number of samples
theta	scalar or length n vector, natural parameter
psi	scalar or length n vector, between 0 and 1, dispersion parameter
r	(Default 2) This should be always 2 to maintain interpretaton of psi. It is kept for future experiment purposes.

Value

random samples from micobin(\theta,\psi).

Examples

hist(rmicobin(1000, 2, 1/3), freq = FALSE)
xgrid = seq(0, 1, length = 500)
lines(xgrid, dmicobin(xgrid, 2, 1/3))
