Abstract

NScluster is an R package used for simulation and parameter estimation for NeymanScott cluster point process models and their extensions. For parameter estimation, NScluster uses the maximum Palm likelihood estimation procedure. As some estimation procedures proposed herein require heavy calculation, NScluster can use parallel computation via OpenMP and achieve significant speedup in some cases. In this paper, we discuss results obtained using a laptop PC and a shared memory supercomputer. In addition, we examine the performance characteristics of parallel computation via OpenMP.

NScluster:一个使用OpenMP对聚类点过程模型进行最大手掌似然估计的R包

NScluster是一个R软件包，用于NeymanScott聚类点过程模型及其扩展的仿真和参数估计。对于参数估计，NScluster使用最大Palm似然估计过程。由于本文提出的一些估计过程需要大量的计算，NScluster可以通过OpenMP使用并行计算，在某些情况下可以获得显著的加速。本文讨论了在笔记本电脑和共享内存超级计算机上得到的结果。此外，我们通过OpenMP检查并行计算的性能特征。
