pp_uniform_phase {carbondate}

Example artificial data - Uniform Phase

Description

40 simulated radiocarbon determinations for which the underlying calendar ages are drawn (uniformly at random) from the period 550–500 cal yr BP.

f(\theta) = U[550, 500]

The observational uncertainty of each determination is set to be 15 {}^{14}C yrs.

The corresponding {}^{14}C ages are then simulated based upon the IntCal20 calibration curve (convolved with the 15 {}^{14}C yr measurement uncertainty):

X_i | \theta_i \sim N(m(\theta_i), \rho(\theta_i)^2 + 15^2),

where m(\theta_i) and \rho(\theta_i) are the IntCal20 pointwise means and uncertainties.

This dataset matches that used in the package vignette to illustrate the Poisson process modelling.
