Analysis of Spatial Gradients in Radiocarbon Dates

Inspired by space-time regressions often performed to assess the expansion of the Neolithic from the Near East to Europe (Pinhasi et al. 2005 ). Test for significant correlations between the (earliest) radiocarbon dates of archaeological sites and their respective distances from a hypothetical center of origin. Distances can be either great-circle or least-cost paths calculated from a friction surface. Both ordinary least squares (OLS) and reduced major axis (RMA) methods are supported (Russell et al. 2014 ). It is also possible to iterate over many sites to identify the most likely origin.
