Webfor hierarchical cluster analyses. For large numbers of observations, hierarchical cluster algorithms can be too time-consuming. The computational complexity of the three popular linkage methods is of order O(n2), whereas the most popular nonhierarchical cluster algorithm, k-means ([R] cluster kmeans; MacQueen 1967), is only of the order O(kn). WebHierarchical clustering also provides an attractive dendrogram, a tree-like diagram showing the degree of similarity between clusters. The dendrogram is a key feature of hierarchical clustering. This tree-shaped graph allows relationships between data points in a dataset to be easily observed and the arrangement of clusters produced by the …
