pcnb: CDF of Conditional Negative Binomial

Description

Cumulative distribution function of 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

pcnb(x, D, r1, r2, lambda)

Arguments

x

a nonempty vector of real numbers.

D

a positive integer.

r1

a positive value.

r2

a positive value.

lambda

a positive value.

Value

A vector providing values of Pr(X <= x | X + Y = D) for each element in x.
