查询词典 hypothetical population

Apodemus agrariuswas predominant in the field accounted for63.16%.The infectious rates of Hattanvirus in Rattus norvegicus and Suncus murinus were7.69%and25.00%,respectively.Hattanvirus was not detected from other animals.The IgG antibody positive rate to Hattanvirus in the serum of hosts of rodents and human population were12.20%and7.00%.

结果 兰坪县3个乡镇共捕捉5属158只啮齿动物，其中居民区中褐家鼠的构成比为91.09%，为优势种；野外高山姬鼠的构成比为63.16%，为优势种。3个乡镇中仅见中排乡捕捉的褐家鼠汉坦病毒抗原的感染率为7.69%（5/65），臭鼠句鼠青为25.00%（1/4），其他捕捉的动物中未查出汉坦病毒抗原；宿主动物血清中汉坦病毒IgG抗体阳性率为12.20%（5/41），其中褐家鼠的阳性率为12.50%（5/40）；人群中汉坦病毒IgG抗体阳性率为7.00%（3/43）。

First, this paper gives an introduction of some methods of unequal probability sampling, their estimators and variance estimators, including sampling with pps with replacement, methods of sampling without replacement suggested by Brewer, Durbin, Sampford , Des Raj , Murthy , Rao-Hartley-Cochran. Then, at the basis of Rao and Bayless's study , we consider that population can be splited two random subpopulations, which are respectively drawn from different infinite super-populations, and compare the stabilities of estimators of the methods that given above.

本文首先从理论上介绍了若干种不等概率抽样方法，它们的估计量、估计量的方差及其估计，其中包括有放回PPZ及PPS抽样，不放回不等概率抽样中的Brewer、Durbin、Sampford、Des Raj，Murthy、Rao-Hartley-Cochran等人的方法；其次，在Rao和Bayless两人就样本单元数n=2的情形对上述抽样方法进行比较的基础上，将总体随机地分成两个子总体，视每个子总体取自不同的线性超总体，在文中，我们利用计算机实现随机分组，并通过画图比较各方法估计量的稳定性，结果表明，对变异系数C.V。
