medv
(Package: mcclust) :
Clustering Method of Medvedovic
Based on a posterior similarity matrix of a sample of clusterings medv obtains a clustering by using 1-psm as distance matrix for hierarchical clustering with complete linkage. The dendrogram is cut at a value h close to 1.

Implements methods for processing a sample of (hard) clusterings, e.g. the MCMC output of a Bayesian clustering model. Among them are methods that find a single best clustering to represent the sample, which are based on the posterior similarity matrix or a relabelling algorithm.
