Recombining observations in cluster analysis: the SAGRA method

This thesis wants to answer the question of how we can recombine this small homogeneous groups to reconstruct the structure of the data set

Recombining partitions from multivariate data: a clustering method on Bayes factors

We introduce SAGRA (Split And Group Recombining Algorithm), a cluster analysis methodology which split the data set into small homogeneous groups and later recombine those groups using Bayes factors.
