项目摘要

Project Summary/Abstract The last decade has seen an explosion of interest in statistical modeling and analysis of spatiotemporally misaligned data and change-of-support problems, where different variables of scientiﬁc interest are observed at disparate scales making them difﬁcult to be coherently modeled. This is especially relevant in environmental public health, where exposure data may be based upon data from monitoring data networks, while climate data are usually available as rasterized outputs from numerical models. The situation is further compounded by our objective of associating these factors with health outcomes (e.g. disease incidence, hospitalizations, mortality and so on), which are reported by public health sources as aggregated data over regions rather than at points. Furthermore, public health researchers today routinely encounter datasets exhibiting high-dimensional spatial misalignment or change-of-support, where “dimension” refers to one or all of the following: (a) the number of spatial units (e.g., geographically referenced coordinates), (b) the number of temporal units (time points) at which the variables have been observed, and (c) the number of outcomes and other variables being studied. We propose a versatile collection of easily implementable and innovative Bayesian statistical methods that, in conjunction with appropriate software, will offer more comprehensive and statistically reliable mapping and analysis for misaligned spatiotemporal data in high-dimensional settings. Our methods and software will help spatial analysts to establish relationships among health outcomes and environmetal and climate-related predictors. Our dissemination efforts will deliver our methodology to a far broader audience of health and environmental researchers and administrators than is currently accessible.

项目概要/摘要在过去的十年里，人们对统计建模和时空分析的兴趣激增数据不一致和支持变化问题，其中观察到具有科学意义的不同变量不同的尺度使得它们很难进行连贯的建模，这在环境方面尤其重要。公共卫生，其中暴露数据可能基于监测数据网络的数据，而气候数据通常可以作为数值模型的栅格化输出获得，情况更加复杂。我们的目标是将这些因素与健康结果（例如疾病发生率、住院治疗、死亡率等），这些数据由公共卫生来源报告为各地区而不是各地区的汇总数据此外，当今的公共卫生研究人员经常遇到表现出高维的数据集。空间错位或支撑变化，其中“维度”指以下一项或全部：(a) 空间单位的数量（例如地理参考坐标），(b) 时间单位的数量（时间）观察变量的点），以及（c）结果和其他变量的数量我们提出了一系列易于实施和创新的贝叶斯统计方法。与适当的软件相结合，将提供更全面和统计上可靠的映射我们的方法和软件将在高维环境中对未对齐的时空数据进行分析。帮助空间分析师建立健康结果与环境和气候相关的关系我们的传播工作将把我们的方法论传播给更广泛的健康和人群。环境研究人员和管理人员比目前可以接触到的更多。
