【摘要】 本文以无放回简单随机抽样(SRSWOR)为例,讨论了相继调查中的轮换样本问题,证明了一个基本定理,从而为充分利用数据信息构造总体特征的估计奠定了基础.文中还提出了若干总体均值、发展速度和增长量的估计量,并由基本定理点出了这些估计量的均值和方差。更多还原

【Abstract】 In this paper we considered the replacement sample problemes in successive sampling under simple random sampling without replacement(SRSWOR). A basic theorem was proved so that it is possible to construct various estimators of population characters in efficient use of data information. We also suggested some estimators of population mean,developing rate and total increasing amount and the mean and variance of the suggested estimators are obtained by the basic theorem.更多还原
