These functions cut hierarchical clusterings into flat clusterings or find the roots of the forest formed by a cut by providing the flat cluster ids of each observation. Form flat clusters from the hierarchical clustering defined by the given linkage matrix. Webon non-representative samples. Correct sampling is thus an essential part of a system of Quality Assurance. Personnel who take samples should receive initial and on-going regular training in the disciplines relevant to correct sampling. This training should include: •sampling plans, •written sampling procedures,

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.
