.rdirspec: Generates from \(Q_i\), the spectral measure of the extremal Dirichlet model

Description

This model was introduced in Coles and Tawn (1991); the present method uses the simulation algorithm of Boldi (2009) for the extremal Dirichlet model

Usage

.rdirspec(n, d, alpha, irv = FALSE)

Value

an n by d sample from the spectral distribution

Arguments

n

sample size

d

dimension of sample

alpha

vector of Dirichlet parameters of dimension d, or \(d+1\) vector with the d Dirichlet parameters and an index of regular variation in \([0, 1]\)

irv

should the usual model (FALSE) or the general scaled version (TRUE) be used
