ADMUR: Ancient Demographic Modelling Using Radiocarbon

Tools to directly model underlying dynamics of radiocarbon date datasets using a Continuous Piecewise Linear (CPL) model framework, or Summed Probability Distributions (SPD) within a simulation framework.

Details

Package to model population dynamics from anthropogenic datasets of dates, including radiocarbon dates and other date such as thermoluminescence. Provides tools to perform two modelling approaches:

1. Summed Probability Distribution generation, and simulation testing. Permits the rejection of a null hypothesis.

2. Directly models the underlying population dynamics using a Continuous Piecewise Linear (CPL) model framework.

The CPL model framework includes tools to: Estimate the dates and magnitude of demographic events (hinge points), both the Maximum likelihood (using DEoptimR search algorithm) and Credible Intervals (using MCMC Metropolis Hastings Algorithm); Perform Goodness of Fit tests; perform model comparison.
