628 radiocarbon determinations collated by Buchanan et al. representing the
ages of distinct archaeological sites found across Canada and North America
during the time of the palaeoindians.

datasets

Performs Bayesian non-parametric calibration of multiple related radiocarbon determinations, and summarises the calendar age information to plot their joint calendar age density (see Heaton (2022) <doi:10.1111/rssc.12599>).
Also models the occurrence of radiocarbon samples as a variable-rate (inhomogeneous) Poisson process, plotting the posterior estimate for the occurrence rate of the samples over calendar time, and providing information about potential change points.
