weightedMean: Compute the weighted arithmetic means of the particles.
Description
This SMC estimate of the means can be used to centre independent Metropolis-Hastings proposals.
Usage
weightedMean(particles, log_weights)
Arguments
particles
npeaks * npart
Matrix of parameter values for each particle.
log_weights
logarithms of the importance weights of each particle.
Value
A vector of means, one for each row.
