摘要
摘要本文探讨了在园艺研究中，与SRS(简单随机抽样)相比，RSS (rank Set Sampling)在提高总体均值估计方面的可行性。我们使用了对印度苹果的调查得出的经验。数值结果表明，在使用相同样本量的具体园艺调查中，RSS程序大大减少了标准误差，因此提供了比SRS更有效的估计。提出了一种简便、准确的方法来管理这一园艺问题。关键词:秩集抽样，简单随机抽样，标准误差，精度。
EFFICIENCY OF RANKED SET SAMPLING IN HORTICULTURAL SURVEYS
DOI: 10.12957/cadest.2015.19114 Abstract In this paper, we explore the feasibility of using RSS (Ranked Set Sampling) in improving the estimates of the population mean in comparison to SRS (Simple Random Sampling) in Horticultural research. We use an experience developed with a survey of apples in India. The numerical results suggest that RSS procedure results in a substantial reduction of standard errors, and thus provides more efficient estimates than SRS, in the specific Horticultural Survey studied, using the same sample size. Then it is recommended as an easy-to-use accurate method to management of this Horticulture problem. Key-words: Ranked Set Sampling, Simple Random Sampling, Standard Error, Accuracy.
