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 (2018).<doi:10.1080/08912963.2017.1336620>.
