Estimates the effective sample size (ESS) of a piecewise deterministic skeleton
EstimateESS(skeletonList, n_batches = 100L, coordinate = -1L,
zeroMeans = FALSE)a piecewise deterministic skeleton (consisting of Times, Points and Velocities) returned by a sampler
optional argument indicating the number of batches to use in the batch means estimation method
if specified, only estimate the ESS of the specified coordinate, otherwise estimate the ESS of all coordinates
if TRUE do not estimate means but assume a centered distribution
Returns a list containing the estimated asymptotic variance, ESS and estimated covariance matrix
