template<typename NT, typename VT, typename MT>
class ESSestimator - #include <ess_window_updater.hpp>
This is a class that updates the effective sample size (ess) of a sample given a new chain using Welford’s algorithm to update the average values and the variance estimates where needed. The chains has to be of the same length. The ess estimation exploits Geyer’s stable estimator for the autocovariance and the Geyer’s conversion to a monotone sequence, given in,
Charles J. Geyer, Practical Markov Chain Monte Carlo, Statistical Science 1992.
