WebYou can use the cophenetic correlation coefficient to compare the results of clustering the same data set using different distance calculation methods or clustering algorithms. For example, you can use the cophenet function to evaluate the clusters created for the sample data set. c = cophenet (Z,Y) c = 0.8615 Webcophenetic is a generic function. Support for classes which represent hierarchical clusterings (total indexed hierarchies) can be added by providing an as.hclust () or, more directly, a cophenetic () method for such a class. The method for objects of class "dendrogram" requires that all leaves of the dendrogram object have non-null labels. Value
