Fig 10. Bayesian 14C models (A and B) for the Tandy excavation.
The models use OxCal’s outlier analysis. Model A includes all data, whereas Model B excludes two outliers in Tandy Stratum 8 (Beta-436538 and Beta-436540). Individual probability distributions before and after modelling are shown in light and dark grey respectively. Calculated transition boundaries are colored green, while date estimates for strata are red. Highest posterior density (hpd) ranges after modelling (68.3% and 95.4%) are marked with bars below each result. Prior and posterior outlier probabilities are indicated in square brackets after the laboratory number and locus. The OxCal code is provided in S1 Appendix.
