摘要: Rohlf, F. James (Ecology and Evolution, State University of New York, Stony Brook, York 11790) 1972. An empirical comparison three ordination techniques in numer ical taxonomy. Syst. Zool., 21:271-280.-This study reports on comparisons Kruskal's nonmetric multidimensional scaling analysis, principal components Gower's coordinates analysis. Nine different sets data were used. It was found that gave better results (as measured by the correlation between distances k-dimensional configuration original distances). also analysis a fit than when missing values present. [Nonmetric scaling; components; coordinates.]
