　　报告摘要：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.
