摘要

本文研究了在总体值之间存在线性趋势的情况下，抽样间隔不等的线性系统抽样问题。得到了预先给定的固定样本量下具有线性趋势的标记总体中不同随机起点的线性系统样本均值及其方差的显式表达式。对所提出的线性系统抽样方案与无置换的简单随机抽样方案、线性系统抽样方案和对角系统抽样方案的效率进行了代数评价，并对某些自然种群进行了评价。结果表明，所提出的线性系统采样方案比上述的采样方案具有更好的性能。

Linear Systematic Sampling with Unequal Sampling Intervals in the Presence of Linear Trend

The present paper deals with the linear systematic sampling with unequal sampling intervals in the presence of linear trend among the population values. As a result, explicit expressions for the linear systematic sample means with different random starts in a labelled population with linear trend for a pre-assigned fixed sample size and the population size together its variance are obtained. The efficiencies of the proposed linear systematic sampling with that of simple random sampling without replacement, linear systematic sampling and diagonal systematic sampling schemes are assessed algebraically and also for certain natural populations. It is observed that the proposed linear systematic sampling performs better than the sampling schemes mentioned above.
