Statistical tools to directly model underlying population dynamics using date datasets (radiocarbon and other).
Various model structures can be compared in a robust formal model comparison framework. Continuous Piecewise Linear (CPL) models are infinitely flexible, and can recover complex population dynamics if enough data is available. Other simpler models include: Uniform, Exponential, Gaussian, Cauchy, Sinusoidal, Logistic and Power law. Taphonomic loss included optionally as a power function.
Posterior parameter estimates of population models, using model likelihoods and a weak uniform prior.
Package also calibrates 14C samples, generates Summed Probability Distributions (SPD), and performs SPD simulation analysis to generate a Goodness-of-fit test for the best selected model. Continuous Piecewise Linear (CPL) models that are flexible to estimate any complex population dynamics
