Using multivariate clustering, it is expected that patterns in human subsistence variability will be found that are consistent with the thery of "attractors" and "repellers." (9580)


multivariate analysis identified 4 discrete clusters consistent with "attractors" separated by gaps that may be "repellors": intensive agriculture, extensive agriculture, pastoralism, and hunting or gathering terrestrial or marine resources.
