rcnb: Random Number Generation from Conditional Negative Binomial

Description

Random number generation from the conditional distribution of X given X + Y = D, where X ~ NB(r1, p1) and Y ~ NB(r2, p2) are drawn from two negative binomials, independent of each other, and assuming p1/p2 = lambda.

Usage

rcnb(n, D, r1, r2, lambda)

Arguments

n

a positive integer.

D

a positive integer.

r1

a positive value.

r2

a positive value.

lambda

a positive value.

Value

n iid draws from X|X+Y=D.
