This work presents the cubature scheme for the fitting of spatio-temporal Poisson point processes. The methodology is implemented in the R Core Team (2024) package stopp (D'Angelo and Adelfio, 2023), published on the Comprehensive R Archive Network (CRAN) and available from https://CRAN.R-project.org/package=stopp. Since the number of dummy points should be sufficient for an accurate estimate of the likelihood, numerical experiments are currently under development to give guidelines on this aspect.
翻译:本文提出了用于拟合时空泊松点过程的数值积分方案。该方法已在R Core Team(2024)发布的stopp软件包(D'Angelo and Adelfio, 2023)中实现,该软件包已在综合R存档网络(CRAN)上发布,可从https://CRAN.R-project.org/package=stopp获取。由于虚拟点的数量应足以精确估计似然函数,目前正在进行数值实验,以就此方面提供指导原则。
