摘要：

Edge‐corrected kernel‐based estimators are proposed for the pair‐correlation function g(t). These estimators are compared by simulation methods with the existing edge‐corrected estimator suggested by FIKSEL (1988, Statistics, 19, 67–75). The results of the simulation study suggests that all the edge‐corrected estimators are almost unbiased. Furthermore, the estimators proposed in this paper have a smaller mean squared error than the existing alternative. Finally, the catoptrophorus semipalmatus nesting pattern is explored.
