"The problem of estimating the variance of the mean from a single systematic sample of a spatially autocorrelated population is investigated by simulation methods. Using a Gaussian Markov stationary autocorrelated model the behaviour of four contenders for the estimator of this variance was studied under various conditions. It was found that a sample based form of the unconditional expected variance of systematic sampling was the most efficient of the four. Further, it was found that using a jackknife autocorrelation estimator instead of the natural autocorrelation estimator did not improve the efficiency of this variance estimator."--Abstract.
