摘要
本文将Vogel和Wong于1979年提出的PFS判别函数引入Fuzzy聚类法中,旨在模糊动态聚类的同时获得一个最佳分类数,并将此方法用于比较国际人口平均寿命。
In 1979,Vogel and Wong presented a peseu-
do F-statistic (PFS) criterion function.It is des-
igned to subdivide an ensemble into an optimal
set of groups.In this paper, we apply this new
criterion function to Fuzzy Clustering Analysis.
The Algorithm for feasible application of PFS
Fuzzy Clustering Method is given. Finally, it
presents the evaluation of the international
mean life based on this new method.
