A Study of the Comparability of External Criteria for Hierarchical Cluster Analysis.

Abstract: Five external criteria were used to evaluate the extent of recovery of the true structure in a hierarchical clustering solution. This was accomplished by comparing the partitions produced by the clustering algorithm with the partition that indicates the true cluster structure known to exist in the data. The five criteria examined were the Rand, the Morey and Agresti adjusted Rand, the Hubert and Arabie adjusted Rand, the Jaccard, and the Fowlkes and Mallows measures. The results of the study indicated that the Hubert and Arabie adjusted Rank index was best suited to the task of comparison across hierarchy levels. Deficiencies with the other measures are noted.

Microcomputer Programs for the Rand Index of Cluster Similarity

Abstract: This paper describes a set of four BASIC computer programs for computing the Rand (1971) index of cluster similarity. The routines calculate the unadjusted Rand index; the separate routines are designed to handle problems of different sizes and alternate methods of data storage.
