摘要

提出了一种空间索引功能数据的扫描方法。扫描统计量来源于功能数据的霍特林检验统计量，扩展了单变量和多变量高斯空间扫描统计量。仿真结果表明，该方法在探测和定位空间簇方面始终优于现有技术。它已被应用于两种类型的实际数据：经济数据，以确定西班牙异常失业率的空间集群；气候数据，以检测英国、尼日利亚、巴基斯坦和委内瑞拉的异常气候变化模式。

A Hotelling spatial scan statistic for functional data: Application to economic and climate data

A scan method for functional data indexed in space has been developed. The scan statistic is derived from the Hotelling test statistic for functional data, extending the univariate and multivariate Gaussian spatial scan statistics. This method consistently outperforms existing techniques in detecting and locating spatial clusters, as demonstrated through simulations. It has been applied to two types of real data: economic data in order to identify spatial clusters of abnormal unemployment rates in Spain and climatic data in order to detect unusual climate change patterns in Great Britain, Nigeria, Pakistan, and Venezuela.

期刊介绍： Spatial Statistics publishes articles on the theory and application of spatial and spatio-temporal statistics. It favours manuscripts that present theory generated by new applications, or in which new theory is applied to an important practical case. A purely theoretical study will only rarely be accepted. Pure case studies without methodological development are not acceptable for publication. Spatial statistics concerns the quantitative analysis of spatial and spatio-temporal data, including their statistical dependencies, accuracy and uncertainties. Methodology for spatial statistics is typically found in probability theory, stochastic modelling and mathematical statistics as well as in information science. Spatial statistics is used in mapping, assessing spatial data quality, sampling design optimisation, modelling of dependence structures, and drawing of valid inference from a limited set of spatio-temporal data.
