## A CENTRAL LIMIT THEOREM FOR m ( n ) AUTOCOVARIANCES

### Journal Article

Many of the fundamental results in time series analysis depend on the joint asymptotic normality of a fixed number m of the sample autocovariances. However, in practice, the m is often chosen after the number of observations, n, is known, with m then treated as fixed. In this paper a Berry‐Esseen type result is proved for m(n) autocovariances for m growing at a certain rate.
