ABSTRACT
Welsch et al calculated a matrix of similarities between each pair of villages on the basis of artefact type presence/absence. The similarity measure they used (Driver's G) was designed to exclude similarity based solely on the fact that a particular type is absent from both villages in a pair. A measure of language similarity between each pair of villages was also constructed, on the basis of current knowledge of the relevant language relations, and the geographical distances between each pair of villages were also calculated. Bivariate and multivariate analyses were then carried out on the corresponding values of the matrices.
