HNBINOM: Hurdle Model for Negative Binomial Distribution

In ebalderama/ZimulatE: Simulates Zero-Inflated, Hurdle, and Double-Hurdle Models

Description

Density, distribution function, quantile function and random generation for the hurdle model using negative binomial distribution with parameters theta, size, and prob.

Usage

dhnbinom(x, theta = 0.5, size = 1, prob = 0.5, log = FALSE)

phnbinom(
  q,
  theta = 0.5,
  size = 1,
  prob = 0.5,
  lower.tail = TRUE,
  log.p = FALSE
)

rhnbinom(n, theta = 0.5, size = 1, prob = 0.5)

Arguments

x, q	vector of quantiles
theta	zero generating parameter (probability of zeros)
size	number of successes (dispersion parameter)
prob	probability of success in each trial. 0 < prob < 1
log, log.p	logical; if TRUE, probabilities p are given as log(p).
lower.tail	logical; if TRUE (default), probabilities are P[X %leq x], otherwise, P[X > x].
n	number of observations
p	vector of probabilities

Value

dhnbinom gives the density, phnbinom gives the distribution function, qhnbinom gives the quantile function, and rhnbinom generates random deviates.
