(4-way) Maximally coupled multinomial resampling with independent residuals

Description

This function performs (4-way) maximally coupled multinomial resampling with independent residuals on each particle system.

Usage

coupled4_maximal_independent_residuals(
  normweights1,
  normweights2,
  normweights3,
  normweights4,
  ndraws,
  rand
)

Arguments

normweights1	normalized weights of first particle system
normweights2	normalized weights of second particle system
normweights3	normalized weights of third particle system
normweights4	normalized weights of fourth particle system
ndraws	number of samples from multinomial distribution
rand	common uniform random variables used for the coupled resampling

Value

a matrix of ancestor indexes of size ndraws x 4.
