A nonparametric estimator for pairwise-interaction point processes
CSIRO Division of Mathematics & Statistics Canberra, ACT 2601, Australia
The paper develops a nonparametric estimator for the class of pairwise-interaction point processes. The estimator is based on an approximation in statistical physics due to Percus and Yevick, which relates the interaction function of a pairwise-interaction point process to its second-order statistics via an integral equation. The results of a simulation study are presented.
