spDates: 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 <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.
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
<doi:10.1371/journal.pone.0087854>). It is also possible to iterate over
many sites to identify the most likely origin.
