A note on weighted third-order statistics for spatial point processes
Keywords:
Third-order statistics, intensity function, point processes
Abstract
In this paper a weighted version of the directional K-statistics, that is the T function, is introduced. The weighted directional statistics is obtained by weighting points by the inverse of the conditional intensity function of the generating point process. Some theoretical results are also provided as a generalization of theorems introduced in Adelfio and Schoenberg (2009).
