Some estimators of population totals from simple random samples containing large units
Articles and reports: 12-001-X197700100006Description: The problem considered is the estimation of population total of some characteristic from a simple random sample containing a few large or extreme observations. The effect of these large units in the sample is to distort the estimate of the population total. It is therefore important to correct the weights for such units or deflate their values at the estimation stage once they have been sampled and identified as unusually large units. In this paper, three estimators which alter the usual sampling weights have been considered. The efficiencies of these estimators have been worked out in terms of the ratio of the variance of the usual estimator of the population total to the mean square error of these estimators. An empirical study of these estimators is also discussed. Issue Number: 1977001Author(s): Hidiroglou, M.A.; Srinath, K.P.Main Product:Survey Methodology
