報告摘要：In this presentation, I will give an overview of some of the latest developments in spatial statistics. First, I will summarize the recent spatial statistics conference in Boulder, Co., where attention was given to spatial statistics for climate and environment. This conference focused on climate change dynamics, their causes, their effects and their future. The conference theme was the perspective of the Earth as a unified system with connections and feedbacks between physical and biological spheres and also human activities. Crucial developments in the methodology were in new scalable methods, spatio-temporal statistics, prediction and statistical aspects of modeling, like spatial and spatio-temporal extremes, attribution and forecasting. Keynote presentations were given on capture-recapture methods and on integrating deep learning into spatial statistics. This will be followed by research carried out at the University of Twente. In a recent study (Osei and Stein, 2023), we developed methodology for bivariate spatial clustering in differential time trends of related tropical diseases. These methods were applied to tropical diseases in particular diarrhea and intestinal parasite infections. In parallel, we developed a Poisson cokriging model for bivariate count data (Payares-Garcia et al., 2023) that allows us to estimate the joint risks of two diseases. These studies were applied to two mosquito-borne diseases in Colombia that showed that our Poisson cokriging successfully performs spatial predictions under different settings. In summary, I will show the liveliness of spatial statistics to address relevant problems in society.
報告人簡介：Alfred Stein教授，任職于荷蘭特溫特大學，地理信息科學與對地觀測學院(Faculty of Geo-Information Science and Earth, ITC)，博士生導師，荷蘭統計與運算協會和荷蘭皇家數學協會成員。2002年至今，他擔任荷蘭特溫特大學地理信息科學和地球觀測學院空間統計與圖像分析方向教授。在此期間，他先后擔任該院副院長(2008)、科學研究部長(2010; 2014)、教育部長(2012)，并在2017年出任特溫特大學教職董事。Stein教授的研究工作主要集中于空間數據與時空數據的統計分析，包括時空采樣優化、遙感影像分析和時空統計學等。由Stein教授創建并擔任主編的《Spatial Statistics》雜志，是統計類期刊當中隸屬一區的雜志，在時空統計學方面處于世界領先地位，收錄了該領域內大量的高質量學術論文。同時，他也是《Environmental and Ecological Statistics》期刊的創始編委，《Soil and Tillage Research》期刊的副主編，《Statistica Neerlandica》、《Geoderma》、《International Journal of Applied Geoinformation and Earth Observation》期刊前主編和《Journal of Agricultural, Biological and Environmental Statistics》期刊前副主編，以及眾多學術期刊的編委。Stein教授已在空間與時空統計學、遙感圖像分析和空間不確定性分析與建模及其他相關領域發表論文300余篇。
