Compute the weighted arithmetic means of the particles.

This SMC estimate of the means can be used to centre independent Metropolis-Hastings proposals.

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.
