The Comparison of Dendrograms by Objective Methods
The purpose of this paper is to present a technique for comparing dendrograms resulting from numerical taxonomic research with one another and with dendrograms produced by conventional methods. One… Expand
A New Statistical Approach to Geographic Variation Analysis
The authors discuss the problems of describing geographic variation data and develop statistical methods for categorizing sets of populations sampled from different localities. The general approach… Expand

neither disappear nor hide under the rug in the near future. Earth Day 1970 was not solely a symptom of another fad. The problems are too persistent and serious for that. Thus, these seven books and… Expand
Brain Size, Cranial Morphology, Climate, and Time Machines [and Comments and Reply]
A bioclimatic model is evaluated as an explanation of variation in cranial capacity among 122 ethnic groups. Distribution of absolute and relative endocranial volume is mapped. Significant… Expand
A Test of Spatial Autocorrelation Analysis Using an Isolation-by-Distance Model.
Using the isolation-by-distance model as an example, we have examined several assumptions of spatial autocorrelation analysis applied to gene frequency surfaces. Gene frequency surfaces generated by… Expand
A QUANTITATIVE APPROACH TO A PROBLEM IN CLASSIFICATION†
The purpose of the study reported in this paper was to determine whether certain statistical procedures might aid persons interested in the relationships among organisms. The objectives of our study… Expand
A METHOD FOR DEDUCING BRANCHING SEQUENCES IN PHYLOGENY
With the advent of relatively objective classifications, such as the phenetic classifications produced by the operational techniques of numerical taxonomy (Sokal and Sneath, 1963), it was inevitable… Expand
