Hypothesis

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)

Note

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.
