| Summary : Bayesian Model to Archaeological Faunal Skeletal Profiles
|
Description :
Tool to perform Bayesian inference of carcass processing/transport
strategy and bone attrition from archaeofaunal skeletal profiles
characterized by percentages of MAU (Minimum Anatomical Units). The
approach is based on a generative model for skeletal profiles that
replicates the two phases of formation of any faunal assemblage:
initial accumulation as a function of human transport strategies and
subsequent attrition.Two parameters define this model: 1) the transport
preference (alpha), which can take any value between - 1 (mostly axial
contribution) and 1 (mostly appendicular contribution) following
strategies constructed as a function of butchering efficiency of
different anatomical elements and the results of ethnographic studies,
and 2) degree of attrition (beta), which can vary between 0 (no
attrition) and 10 (maximum attrition) and relates the survivorship of
bone elements to their maximum bone density. Starting from uniform
prior probability distribution functions of alpha and beta, a Monte
Carlo Markov Chain sampling based on a random walk Metropolis-Hasting
algorithm is adopted to derive the posterior probability distribution
functions, which are then available for interpretation. During this
process, the likelihood of obtaining the observed percentages of MAU
given a pair of parameter values is estimated by the inverse of the
Chi2 statistic, multiplied by the proportion of elements within a 1
percent of the observed value. See Ana B. Marin-Arroyo, David Ocio
