Short summary
Bayesian modelling is often used to refine numerically dated chronological sequences, e.g., by making use of stratigraphic constraints. First, a high-resolution dataset based on luminescence dating is modelled with the dedicated R package BayLum. Then, three Bayesian modelling tools – namely BayLum, Chronomodel and OxCal – are compared using a high-resolution, radiocarbon dataset. Modelling artefacts are identified; the strengths and weaknesses of the models are discussed.
