dwdcomppareto {CompPareto}

The probability mass function (pmf) of a discrete composite distribution with Pareto tail

Description

dwdcomppareto returns the pmf of a discrete composite distribution with a Pareto upper tail at a point x, with a specified distribution at the lower tail.

Usage

dwdcomppareto(x, spec, alpha, theta, log = FALSE, ...)

Arguments

x

A scalar or vector of nonnegative integer values at which the probability mass needs to be evaluated

spec

The selection of the lower tail (head) distribution

alpha

The shape parameter of the Pareto distribution

theta

The scale parameter of Pareto, also serve as the location parameter of the composite model

log

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

...

The parameter of the lower tail (head) distribution

Value

an object of the same length of x as the probability mass evaluated at x

Examples

x<-1:100
dwdcomppareto(x, "lnorm", 0.4, 1, meanlog = 1, sdlog = 0.8)
dwdcomppareto(x, "weibull", alpha = 1.5, theta = 1.5, shape = 2, scale = 2)
