In fclust: Fuzzy Clustering

Cluster size

Description

Produces the sizes of the clusters in the hard clustering sense (objects are considered to be assigned to clusters only if the corresponding membership degree are >=0.5).

Usage

 cl.size.H (U)

Arguments

U	Membership degree matrix

Details

An object is assigned to a cluster according to the maximal membership degree provided that such a maximal membership degree is >=0.5, otherwise it is assumed that an object is not assigned to any cluster.

Value

clus.size

Vector containing the sizes of the clusters
