Second-Order Analysis of Inhomogeneous Spatial Point Processes With Proportional Intensity Functions
强度函数成比例的非齐次空间点过程二阶分析
We consider pairs of spatial point processes with intensity functions sharing a common multiplicative term. We introduce two novel approaches to estimating the pair correlation function for one of the point processes by treating the other as a baseline so as to account for the unspecified part of the intensity functions. The first approach is based on nonparametric kernel-smoothing, whereas the second approach uses a conditional likelihood estimation approach to fit a…
