动态空间和网络抽样

Dynamic spatial and network sampling

Steven K. Thompson

摘要:

本文考虑了在动态网络和时空环境中的抽样和干预的一些设计。样本主要通过追踪网络链接在人口中传播,尽管也可以使用随机抽样或空间设计。为了研究不同设计的有效性,通过模拟来研究如何找到进行观察和引入干预的单元。为此目的,一个动态的空间网络模型开发的基础上简单的随机过程。所考虑的抽样过程既有获取过程,也有从样本中增加和删除单位的消耗过程。通过所产生的平衡分布的变化,或更详细地说,通过干预战略所产生的样本路径的分布,来评估采用给定抽样设计的干预措施的效果。

英文摘要:

This paper considers some designs for sampling and interventions in dynamic networks and spatial temporal settings. The sample spreads through the population largely by tracing network links, although random sampling or spatial designs may be used in addition. To investigate the effectiveness of different designs for finding units on which to make observations and introduce interventions is investigated through simulations. For this purpose a dynamic spatial network model is developed based on simple stochastic processes. The sampling processes considered have both acquisition processes and attrition process by which units are added and removed from the sample. The effect of an intervention introduced with a given sampling design is assessed by the change in the resulting equilibrium distribution or, in more detail, by the distribution of sample paths resulting from the intervention strategy.
