WebThe cophenetic distance between observations i and j is simply the distance between clusters s and t. scipy.cluster.hierarchy. correspond (Z, Y) ¶ Checks if a linkage matrix Z and condensed distance matrix Y could possibly correspond to one another. They must have the same number of original observations for the check to succeed. WebHierarchical Clustering Produce nested sets of clusters Hierarchical clustering groups data into a multilevel cluster tree or dendrogram. If your data is hierarchical, this technique can help you choose the level of clustering that is most appropriate for your application. Functions Topics Hierarchical Clustering

WebCophenetic correlation In statistics, and especially in biostatistics, cophenetic correlation (more precisely, the cophenetic correlation coefficient) is a measure of how faithfully a dendrogram preserves the pairwise distances between the original unmodeled data points. http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/stats/cophenet.html
