摘要

我们使用人口与健康调查(DHS)数据来评估随机空间位移对分析的影响，这些分析涉及分配辅助面积和点特征数据的协变量值。我们介绍了一种确定最大概率协变量(MPC)的方法，并将其与朴素协变量(NC)选择方法在获得真正感兴趣的协变量方面进行了比较。MPC选择方法通过增加选择正确协变量的概率而优于NC选择方法。建议的指南还解决了辅助面和点特征的特征如何导致协变量分配的不确定性。

Influence of Demographic and Health Survey Point Displacements on Point-in-Polygon Analyses.

We use Demographic and Health Survey (DHS) data to evaluate the impact of random spatial displacements on analyses that involve assigning covariate values from ancillary areal and point feature data. We introduce a method to determine the maximum probability covariate (MPC), and compare this to the naive covariate (NC) selection method with respect to obtaining the true covariate of interest. The MPC selection method outperforms the NC selection method by increasing the probability that the correct covariate is chosen. Proposed guidelines also address how characteristics of ancillary areal and point features contribute to uncertainty in covariate assignment.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
