Benhc: Performs bootstrap ensemble hierarchical clustering for...
In EnsCat: Clustering of Categorical Data

Description Usage Arguments Details References Examples

This function performs a bootstrap ensemble hierarchical clustering of categorical data, as described in details below.

1	Benhc(x, En)

`x`	A nxp data matrix or data frame; n is the number of observations and p is the number of dimensions.

`En`	Number of clusterings to include in the ensemble, i.e., cardinality of the ensemble.

The function 'Benhc' generates a dissimilarity matrix via the bootstrap ensemble. The ensembled dissimilarity matrix is generated using the same procedure as described for the function ‘enhc’ except that each clustering is based on a bootstrap sample of the data. The number of clusters for each clustering is selected randomly from {2,...,sqrt(n)}.

#data('zoo')
### zoo includes the zoo data downloaded from UCI
### Machine Learning Repository
### Calculate ensemble dissimilarities with 150 ensemble members
#disten<-Benhc(zoo$obs,En=150)
### This function performs a hierarchical cluster analysis using
### dissimilarities obtained by the ensembling procedure in Benhc
#en<-hclust(disten,method='average')
### A plot of the dendrogram can be generated by
#plot(en,label=zoo$lab)
