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
