In rchan26/hierarchicalFusion: Divide-and-Conquer Monte Carlo Fusion

Generalised Monte Carlo Fusion (rejection sampling) [on a single core]

Description

Generalised Monte Carlo Fusion with bivariate Gaussian target

Usage

fusion_biGaussian(
  N,
  m,
  time,
  samples_to_fuse,
  mean_vec,
  sd_vec,
  corr,
  betas,
  precondition_matrices,
  inv_precondition_matrices
)

Arguments

N	number of samples
m	number of sub-posteriors to combine
time	time T for fusion algorithm
samples_to_fuse	list of length m, where samples_to_fuse[c] containing the samples for the c-th sub-posterior
mean_vec	vector of length 2 for mean
sd_vec	vector of length 2 for standard deviation
corr	correlation value between component 1 and component 2
betas	vector of length m, where betas[c] is the inverse temperature (beta) for c-th sub-posterior (can also pass in one number if they are all at the same inverse temperature)
precondition_matrices	list of length m, where precondition_matrices[[c]] is the precondition matrix for sub-posterior c

Value

samples: fusion samples

iters_rho: number of iterations from the first accept/reject step (rho)

iters_Q: number of iterations from the second (diffusion) accept/reject step (Q)
