stratRejectionSampler_exp: Stratified rejection sampler for multivariate exponential point process

Description

Simulate data using a stratified rejection sampler from a point process with an isotropic multivariate exponential decay kernel.

Usage

stratRejectionSampler_exp(
  numPoints,
  lowerCoords,
  upperCoords,
  s,
  windowIntensities,
  lambda
)

Value

A matrix of x- and y-coordinates of the generated points. One row corresponds to one point.

Arguments

numPoints

Number of spatial points to generate.

lowerCoords, upperCoords

Matrices of lower and upper x- and y-coordinates of a set of detection windows. One row for each window.

s

Vector of x- and y-coordinates of of the isotropic multivariate exponential distribution mean.

windowIntensities

Vector of integrated intensities over all detection windows.

lambda

Rate parameter of the isotropic multivariate exponential distribution.

Examples

numPoints <- 10
lowerObsCoords <- matrix(c(0, 0, 1, 0, 0, 1, 1, 1), nrow = 4, byrow = TRUE)
upperObsCoords <- matrix(c(1, 1, 2, 1, 1, 2, 2, 2), nrow = 4, byrow = TRUE)
s <- c(1, 1)
windowIntensities <- c(1:4)
lambda <- 0.1
stratRejectionSampler_exp(numPoints, lowerObsCoords, upperObsCoords, s, windowIntensities, lambda)
