ZIDGP: Zero-inflated Discrete Generalized Pareto Distribution

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

Description

Density, distribution function, quantile function and random generation for the zero-inflated discrete generalized Pareto distribution with parameters theta, mu, scale, and shape.

Usage

dzidgp(x, theta = 0.5, mu = 0, scale = 1, shape = 1, log = FALSE)

pzidgp(
  q,
  theta = 0.5,
  mu = 0,
  scale = 1,
  shape = 1,
  lower.tail = TRUE,
  log.p = FALSE
)

qzidgp(
  p,
  theta = 0.5,
  mu = 0,
  scale = 1,
  shape = 1,
  lower.tail = TRUE,
  log.p = FALSE
)

rzidgp(n, theta = 0.5, mu = 0, scale = 1, shape = 1)

Arguments

x, q	vector of quantiles
theta	zero-inflation parameter (probability of zeros)
mu	location parameter
scale	scale parameter
shape	shape parameter
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].
p	vector of probabilities
n	number of observations

Value

dzigp gives the density, pzigp gives the distribution function, qzigp gives the quantile function, and rzigp generates random deviates.
