Inferences to the patterns. These were processual, looking for patterns that showed economic and political patterns. People tested the different sampling strategies, systematic unaligned, versus stratified for example. New focus on resource use and political development. Based on 3 models of point distributions, sites are locating near each other or not using the Nearest Neighbor statistic and the patterning of settlements.
Clustering is being associated, regular is antagonistic, random is in the middle.
Took site patterns through time, Texcoco region, east of the lake Tenochitlan. Formative phases, maps show site locations and site sizes. Identified the zones that the settlements tended to be placed in. In terms of political development, Earle noted the nearest neighbors of the sites by size, and noted that even the larger sites were clustered in this zone. This is the time that Teotihuacan was developing to the north and that all sites were focusing on that site.
