draw_rc_meas_using_date: Simulate radiocarbon measurements from input calendar dates

In eehh-stanford/baydem: Bayesian Tools for Reconstructing Past and Present Demography

Simulate radiocarbon measurements from input calendar dates

Description

Given input calendar dates t_e, simulate the radiocarbon measurement process to yield a fraction modern and uncertainty. error_spec is a list with named type and additional fields specifying the parameters. Currently only type unif_fm (for uniform fraction modern) is supported, which makes a uniform draw on the interval min to max for the uncertainty of the fraction modern value, where min and max are fields in error_spec giving the boundaries of the uniform draw. By default, t_e is assumed to be calBP, but can be AD (more more precisely, 1950 - BP value) if is_AD is True.

Usage

draw_rc_meas_using_date(t_e, calib_df, error_spec, is_AD = F)

Arguments

t_e	A vector of event dates (calBP by default)
calib_df	The calibration dataframe, with columns year_BP, uncal_year_BP, and uncal_year_BP_error
error_spec	A list with entries type and parameter values specifying how to add uncertainty to the simulated measurement. Currently, only type = "unif_fm" is supported, for which the parameters min and max must be in error_spec.
is_AD	Whether t_e is cal_BP or AD (optional; default: FALSE)
