摘要
应用非参数核密度估计方法，可以由样本直径结构很好地描述总体直径结构，而无需假定总体的直径分布。本文采用计算机模拟技术，比较了核方法与直方图方法及列点法在描述总体时的优劣，结论是核方法优于直方图方法。
The population diameter structure can well be described by using nonparametric kernel method based on the sample data without assuming the population diameter distribution. The results of the computer simulation have showed that nonparametric kernel method is better than both histogram method and diameter list method in obtaining the population diameter structure.
