Hierarchical method

WebClustering methods are to a good degree subjective and in fact I wasn't searching for an objective method to interpret the results of the cluster method. I was/am searching for a robust method to determine the best number of cluster in hierarchical clustering in R that represents best my data structure. WebBayesian hierarchical modelling is a statistical model written in multiple levels (hierarchical form) that estimates the parameters of the posterior distribution using the Bayesian method. The sub-models combine to form the hierarchical model, and Bayes' theorem is used to integrate them with the observed data and account for all the uncertainty that is present.
