WebSep 13, 2011 · By about 1980 phenetic approaches had been pushed aside by phylogenetic systematics, but Sneath and Sokal’s work is still regarded by mathematical clusterers as the most important founding work in their field. The most widely-used of Sneath’s methods is the UPGMA clustering method (independently also invented by F. J. Rohlf). WebPhenetics (as numerical taxonomy) emerged in the late 1950s, its origin associated with, among others, Charles Michener, Arthur Cain, and especially Robert Sokal and Peter Sneath.In Sokal and Sneath's (1963) Principles of Numerical Taxonomy, any evolutionary approach is avoided in favor of an operational method based on a direct comparison of …

WebThe percentage of improvement with respect to the best classical dissimilarity metric (Sokal-Sneath) is within the interval [0.7, 6]. In addition, the obtained new metric clearly outperforms the results of the Euclidean based p-persistence. Regarding redundancy, the proposed approach outperforms flooding and it is closed to Sokal-Sneth metric. WebP H SNEATH, R R SOKAL. PMID: 13914561 DOI: 10.1038/193855a0 No abstract available.
