qcnb: Quantile Function of Conditional Negative Binomial
Description
Quantile 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
qcnb(p, D, r1, r2, lambda)
Arguments
p
a nonempty vector of probabilities (0 <= p[i] <= 1 for all i).
D
a positive integer.
r1
a positive value.
r2
a positive value.
lambda
a positive value.
Value
A vector x such that x[i] = Inf{x in 0:D, p[i] <= Pr(X <= x | X + Y = D)} for all i.
