Abstract
In most books on time series analysis, estimators of the variance and autocovariance for a stationary process are discussed under the assump tion that the process mean is known. Here we illustrate that, if the p rocess mean is unknown and hence is estimated by the sample mean, thes e estimators have some surprising properties.
