"""Flexible Procedures for Clustering.
Various methods for clustering and cluster validation. Fixed point
clustering. Linear regression clustering. Clustering by merging Gaussian
mixture components. Symmetric and asymmetric discriminant projections for
visualisation of the separation of groupings. Cluster validation
statistics for distance based clustering including corrected Rand index.
Standardisation of cluster validation statistics by random clusterings and
comparison between many clustering methods and numbers of clusters based on
this. Cluster-wise cluster stability assessment. Methods for estimation
of the number of clusters: Calinski-Harabasz, Tibshirani and Walther's
prediction strength, Fang and Wang's bootstrap stability.
Gaussian/multinomial mixture fitting for mixed continuous/categorical
variables. Variable-wise statistics for cluster interpretation. DBSCAN
clustering. Interface functions for many clustering methods implemented in
R, including estimating the number of clusters with kmeans, pam and clara.
Modality diagnosis for Gaussian mixtures. For an overview see
package?fpc."""
