放回抽样下HT估计量的性质及应用

放回抽样下传统的估计方法是采用Hansen-Hurwitz估计。而放回抽样下HH估计量并不是一致最小方差无偏估计，本文提出了另一种估计方法，即采用Horvitz-Thompson估计，并论证了放回抽样下HT估计量的三条定理，及与HH估计量的比较。然后以放回简单随机抽样和PPS抽样为例，通过理论公式、计算机模拟以及具体案例，进行更具体的分析。说明在一定条件下，HT估计量相对更优。在实际应用中，本文也提出了通过比较方差估计作为选取估计量的准则。

The Property and Application of Horvitz-Thompson Estimator of Replacement Sampling

Hansen-Hurwitz(HH) estimator is a traditional estimation method of replacement sampling, but it isn’t always the best. This paper proposes Horvitz-Thompson(HT) estimator which is another choice. This paper also takes simple random sampling with replacement and sampling with probability proportional to size for examples, makes a thorough comparison on two methods. The theoretical formulas, computer simulations and the specific example show that HT estimator is better than HH estimator in sampling with replacement under a certain condition. In fact, we can choose the estimator of which the variance estimation is smaller. Fenceress specif superefficiency permanence logo rumania cornicle afterpunching?
