A non-model-based approach to bandwidth selection for kernel estimators of spatial intensity functions
提出一种新的带宽选择方法，用于空间点过程强度函数的核估计，基于Campbell公式的优化准则，无需模型假设和数值积分。
We propose a new bandwidth selection method for kernel estimators of spatial point process intensity functions. The method is based on an optimality criterion motivated by the Campbell formula applied to the reciprocal intensity function. The new method is fully nonparametric, does not require knowledge of higher-order moments, and is not restricted to a specific class of point process. Our approach is computationally straightforward and does not require numerical approximation of integrals.
