 无限总体
 infinite population
 The paper explains the variance of sample means and that of sample proportion with the unrepeatable sampling in finite population are more complicated than with the repeatable sampling and with the unrepeatable sampling in infinite population. In that case, both need to be corrected according to the total of population units and added a factor called finite population correction. 说明有限总体不重复抽样方式相比于重复抽样方式和无限总体不重复抽样方式,样本均值方差和样本成数方差较复杂,需根据总体单元总数进行修正,增加一个有限总体修正系数的因子. 短句来源

 Finite and Infinite Populations 有限总体和无限总体 短句来源 Inverse sampling method is usually used in solving rare item problem (P<10%) in sample surveying. Adversely, it would easily lead to serious bias if applying other general method of drawing, based on discussing the theory of inversed sampling in detail, the author illustrates some simple and effective methods on ratio P estimation and sample size confirmation. 对于稀少项目占总体比例P的抽样调查,若P比较少用一般简单的抽样方法进行抽样调查,容易产生比较大的偏差,所以通常采用逆抽样的方法,本文较为系统地讨论了逆抽样的一般理论,给出了针对无限总体与有限总体进行逆抽样时P的估计方法,并从理论上给出了这个估计的一个简捷而有效的均方误差公式。 短句来源

 infinite population
 An infinite number of loci determining the traits, directional and truncation selection, discrete generations and infinite population size were assumed. The equations assume an infinite population and account for the effects of selection. In this note we show that this finding depends on the use of the infinite population ESS (Maynard-Smith, Evolution and the theory of games, Cambridge University Press, Cambridge, UK, 1982). Rawlsian equity and generalised utilitarianism with an infinite population The paper explores a model of equilibrium selection in coordination games, where agents from an infinite population stochastically adjust their strategies to changes in their local environment. 更多
