论文摘要
空间和生态统计领域中一个不断发展的问题是优先采样，其中由于样本数据位置与感兴趣的响应之间的关系，可能存在偏见。该研究领域与调查方法中的长期参考抽样问题具有显着相似之处，尽管有一些重要的区别。为了促进这两个问题域内和之间的协作努力，我们在两个问题陈述之间进行比较和对比。具体而言，我们回顾了许多可用于解决这些问题的解决方案，并指出建模技术的重要差异。此外，我们构建了一系列仿真研究，以检查一些可用于优先采样的方法，以及分析重金属生物监测数据的比较。
An evolving problem in the field of spatial and ecological statistics is that of preferential sampling, where biases may be present due to a relationship between sample data locations and a response of interest. This field of research bears a striking resemblance to the longstanding problem of informative sampling within survey methodology, although with some important distinctions. With the goal of promoting collaborative effort within and between these two problem domains, we make comparisons and contrasts between the two problem statements. Specifically, we review many of the solutions available to address each of these problems, noting the important differences in modeling techniques. Additionally, we construct a series of simulation studies to examine some of the methods available for preferential sampling, as well as a comparison analyzing heavy metal biomonitoring data.
