Visualizing spatial processes using Ripley's correction: an application to bodily-injury car accident location
Résumé
In this paper, we investigate (and extend) Ripley's circumference method to correct bias of density estimation of edges (or frontiers). We provide a simple technique - based on optimal bandwidth using Gaussian kernels - to compute efficiently weights to correct border bias on frontiers of the region of interest. An illustration on location of bodily-injury car accident in the western part of France is discussed.
