Abstract

The batch-means process arising from an arbitary autoregressive moving-average (ARMA) process time series is derived. As side results, the variance and correlation structures of the batch-means process as functions of the batch size and parameters of the original process are obtained. Except for the first-order ARMA process, for which a closed-form expression is obtained, the parameters of the batch-means process are determined numerically.
