不等概率抽样估计的原理与应用

Principle and Application of Sampling Estimation for Unequal Probability

不等概率抽样估计是一种十分有效的抽样推断方法,它在实践中有着广泛的应用,采用不等概率抽样修正等概率抽样,可以弥补抽样调查中等概率抽样估计的不足。以对2007年全国各地区接待的入境旅游人数进行估计为例,在不等概率抽样原理的基础上,抽取样本,采用适当的方法进行测算,才能达到提高抽样估计效率的目的。

Sampling estimation for unequal probability is a very effective method for sample inference,and is applied to practice extensively.It adopts the probability sampling method of unequal probability sampling correction and can makes up the insufficiency of equal probability sampling estimation in the spot check.Taking the case of estimating the international tourist arrivals from the whole country in 2007,based on the unequal probability sampling theory,the author takes samples and adopts the proper way to mea...
