Analysis of Spatial Gradients in Radiocarbon Dates

CRAN Package

Inspired by space-time regressions often performed to assess the expansion of the Neolithic from the Near East to Europe (Pinhasi et al. 2005 [doi:10.1371/journal.pbio.0030410]). Test for significant correlations between the (earliest) radiocarbon dates of archaeological sites and their respective distances from a hypothetical center of origin. Both ordinary least squares (OLS) and reduced major axis (RMA) methods are supported (Russell et al. 2014 [doi:10.1371/journal.pone.0087854]). It is also possible to iterate over many sites to identify the most likely origin.
