在本文中，六个无分布（非参数）体视学方法解决威克塞尔的微粒问题，即确定的直径分布的球体嵌入在一个不透明的标本，从他们的轮廓在平面截面上的直径的数值稳定性，敏感性的基础上的分布和一定的误差标准进行了比较。该研究基于几种类型的球体直径分布（一点、正态、指数、对数正态）的模拟研究结果。对样本数据分组的方法选择、样本容量和最佳分类数提出了建议。
In this paper six distribution‐free (nonparametric) stereological methods for the solution of Wicksell's corpuscle problem—i.e. the determination of the distribution of diameters of spheres embedded in an opaque specimen from the diameters of their profiles on plane sections—are compared as regards their numerical stability, sensitivity to underlying distributions and certain error criteria. The study is based on the results of simulation studies for several types of distribution (one‐point, normal, exponential, logarithmic normal) of sphere diameters. Recommendations are suggested for the choice of methods, sample size and the optimal number of classes for grouping sample data.
