Cluster Density Analysis of Dimensional Socio-Cultural Evolution Models



A quantitative method is briefly described whereby societal density contours may be constructed at successive cross-sectional levels of the three-dimensional, branching, socio-cultural evolution models described in American Anthropologist 1969, 71(5): 864–870. Considered with the branching model, these cross-sections help to reveal the underlying evolutionary structure, discounting random variations in the sample or excessively complex branchings in large-sample models.
