poistweedie {poistweedie}

Poisson-Tweedie (Some discrete exponential dispersion models)

Description

Density, Log of density, variance for the Poisson-Tweedie family of distributions

Usage

poistweedie(x, n, p, mu, lambda, theta0, lower.tail = TRUE, log.p = FALSE, 
    fonction = "PROBABILITE")
poisson(x, n, p, lambda1, lower.tail = TRUE, log.p = FALSE, 
    fonction = "PROBABILITE")
nbinomiale(x, n, p, lambda1, p1, lower.tail = TRUE, log.p = FALSE, 
    fonction = "PROBABILITE")

Arguments

x

vector of (non-negative integer) quantiles.

p

is a real index related to a precise model.

p1

is a real index related to a precise model.

n

non-negative integer

mu

the mean.

lambda

the dispersion parameter.

lambda1

the dispersion parameter.

theta0

the canonical parameter.

log, log.p

logical; if TRUE, probabilities p are given as log(p).

lower.tail

logical; if TRUE (default), probabilities are P[X <= x], otherwise, P[X > x].

fonction

is a string
