متن کاملEstimation of spatio-temporal correlations of prehistoric population and vegetation in North America
We discuss a simple methodology to enable a statistical comparison of human population with the vegetation of North America over the past 13000 years. Nonparametric kernel methods are applied for temporal and spatial smoothing of point data obtained from the Neotoma Paleoecology Database and the Canadian Archaeological Radiocarbon Database, which results in sequences of maps showing the develop...
