有限总体QR-型予测的影响统计量

INFLUENCE STATISTIC FOR QR PREDICTOR IN FINITE POPULATION

本文利用超总体模型,得到了Wright引进的QR-型予测的影响统计量及统计量的分布。并把这些结果应用到比率模型中人们所熟悉的几种子测。如Horvitz-Thompson比予测。

By using a superpopulation model, this paper obtains the influence statistic for QR predictor introduced by wright.[1] The distribution of the statistic is also given. The results are applied to many familiar predictors in the simple ratio model, e.g.,Horvitz-Thompson Ratio, Best linear ζ-unbiased and Brewer's predictor, etc.
