Description

The Zero-Inflated Negative Binomial Distribution

Usage

rzinb(n, size, mu, rho)

Arguments

n

The number of random values to return.

size

The dispersion paramater used in dnbinom.

mu

The mean parameter used in dnbinom.

rho

Value

Examples

x <- rzinb(10, 1, 10, 0.1)
p <- pzinb(x, 1, 10, 0.1)
y <- qzinb(p, 1, 10, 0.1)
all(x == y)
# Compute P(0 < X < 5) for X ~ ZINB(1, 10, 0.1)
sum(dzinb(0:5, 1, 10, 0.1))
