Generates from Qi, the spectral measure of the pairwise Beta model

Description

This model was introduced in Cooley, Davis and Naveau (2010). The sample is drawn from a mixture and the algorithm follows from the proof of Theorem 1 in Ballani and Schlather (2011) and is written in full in Algorithm 1 of Sabourin et al. (2013).

Usage

.rpairbetaspec(n, d, alpha, beta)

Arguments

n

sample size

alpha

concentration parameter

beta

vector of all pairwise component (lexicographic order, by row)

Value

a matrix of samples from the angular distribution

an n by d sample from the spectral distribution
