Influence of Demographic and Health Survey Point Displacements on Raster-Based Analyses. 人口与健康调查点位移对栅格分析的影响。
IF 1.9 Q3 DEMOGRAPHY Pub Date : 2016-07-01 Epub Date: 2015-06-23 DOI: 10.1007/s40980-015-0013-1

With this paper we explore the sensitivity of study results to spatial displacements associated with Demographic and Health Survey (DHS) data in research that integrates ancillary raster data. Through simulation studies, we found that the impact of DHS point displacements on raster-based analyses can be moderated through the generation of covariates representing average values from neighborhood buffers. Additionally, raster surface characteristics (i.e., spatial smoothness) were found to affect the extent of bias introduced through point displacements. Although simple point extraction produced unbiased estimates in analyses involving smooth continuous surfaces, it is not recommended in analyses that involve categorical raster surfaces.

在本文中,我们探讨了在整合辅助光栅数据的研究中,研究结果对与人口与健康调查(DHS)数据相关的空间位移的敏感性。通过模拟研究,我们发现DHS点位移对基于栅格的分析的影响可以通过生成代表邻域缓冲区平均值的协变量来缓和。此外,发现栅格表面特征(即空间平滑度)会影响通过点位移引入的偏差程度。虽然简单的点提取在涉及光滑连续表面的分析中产生无偏估计,但不建议在涉及分类光栅表面的分析中使用。

Influence of Demographic and Health Survey Point Displacements on Point-in-Polygon Analyses. 人口与健康调查点位移对点-多边形分析的影响。
IF 1.9 Q3 DEMOGRAPHY Pub Date : 2016-07-01 Epub Date: 2015-06-20 DOI: 10.1007/s40980-015-0015-z

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.

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 Distance-Based Analyses. 人口和健康调查点位移对基于距离的分析的影响。
IF 1.9 Q3 DEMOGRAPHY Pub Date : 2016-07-01 Epub Date: 2015-06-23 DOI: 10.1007/s40980-015-0014-0

We evaluate the impacts of random spatial displacements on analyses that involve distance measures from displaced Demographic and Health Survey (DHS) clusters to nearest ancillary point or line features, such as health resources or roads. We use simulation and case studies to address the effects of this introduced error, and propose use of regression calibration (RC) to reduce its impact. Results suggest that RC outperforms analyses involving naive distance-based covariate assignments by reducing the bias and MSE of the main estimator in most settings. Proposed guidelines also address the effect of the spatial density of destination features on observed bias.

我们评估了随机空间流离失所对分析的影响,这些分析涉及从流离失所的人口和健康调查(DHS)集群到最近的辅助点或线特征(如卫生资源或道路)的距离测量。我们使用模拟和案例研究来解决这一引入误差的影响,并建议使用回归校准(RC)来减少其影响。结果表明,在大多数情况下,RC通过减少主估计器的偏差和MSE,优于涉及基于初始距离的协变量分配的分析。建议的指南还解决了目标特征的空间密度对观察到的偏差的影响。
