摘要
文章针对经济社会领域的具有中心区域优势向外辐射、传递功能的圆形区域调查问题,提出了圆形区域的等比分位抽样的概念,构造出均值的无偏估计量,讨论了这种方法的抽样误差,在适当的条件下,得出了该抽样方法优于简单随机抽样和分位点的最优划分的结论。并结合西安市酒店业实际调查资料给出了完整的抽样方案设计和具体计算结果。
Aiming at the problem of circular area survey in the economic and social field, which radiates and transmits the advantage of central area, this paper proposes the concept of equal probability sampling in circular area, constructs the unbiased estimator of mean value, discusses the sampling error of this method, and draws the conclusion that the proposed sampling method is superior to simple random sampling and the optimal classification of quantile. Finally, Combined with the actual survey data of Xi’an hotel industry, the paper presents the complete sampling scheme design and specific calculation results.
