While discriminant function analysis is an inherently Bayesian method, researchers attempting to estimate ancestry in human skeletal samples often follow discriminant function analysis with the calculation of frequentist-based typicalities for assigning group membership. Such an approach is problematic in that it fails to account for admixture and for variation in why individuals may be classified as outliers, or non-members of particular groups. This paper presents an argument and methodology for employing a fully Bayesian approach in discriminant function analysis applied to cases of ancestry estimation. The approach requires adding the calculation, or estimation, of predictive distributions as the final step …

The way that immigrants integrate to recipient societies has been discussed for decades, mainly from the perspective of the social sciences. Uruguay, as other American countries, received different waves of European immigrants, although the details of the process of assimilation, when occurred, are unclear. In this paper, we use genetic markers to understand the process experienced by the Basques, one of the major migration waves that populated Uruguay, and its relation to other immigrants as well as to Native American and African descendants. For this purpose, we analyze the allele frequencies of ten ALU loci (A25, ACE, APOA1, B65, F13B, …
