Description: 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.
