In crandep: Network Analysis of Dependencies of CRAN Packages

Probability mass function (PMF) of 2-component discrete extreme value mixture distribution

Description

dmix2 returns the PMF at x for the 2-component discrete extreme value mixture distribution. The components below and above the threshold u are the (truncated) Zipf-polylog(alpha,theta) and the generalised Pareto(shape, sigma) distributions, respectively.

Usage

dmix2(x, u, alpha, theta, shape, sigma, phiu)

Arguments

x	Vector of positive integers
u	Positive integer representing the threshold
alpha	Real number, first parameter of the Zipf-polylog component
theta	Real number in (0, 1], second parameter of the Zipf-polylog component
shape	Real number, shape parameter of the generalised Pareto component
sigma	Real number, scale parameter of the generalised Pareto component
phiu	Real number in (0, 1), exceedance rate of the threshold u

Value

A numeric vector of the same length as x
