A note on robust density estimation for spatial point patterns
Department of Statistics, University of Newcastle upon Tyne
The author's earlier analytical results on the robustness of distance-based estimators of density are supplemented by a simulation study, with particular attention being given to various types of aggregated spatial point patterns. In addition, some remarks on heterogeneous patterns are made. Finally, the results of an application to data on tree locations are described.
