Predictive distribution of date

Description

Predictive distribution of date

Usage

undated_sample(data1, data2, level = 0.95)

Arguments

data1	Numeric vector containing the output of the MCMC algorithm for the begining of interval
data2	Numeric vector containing the output of the MCMC algorithm for the end of interval
level	Probability corresponding to the desired level of confidence. @return A list with the following components:

Details

Simulate the sample from the predictive distribution of an undated sample in stratigraphic constraint between two dates. The input is an MCMC sample simulated from the joint posterior distribution of these dates.
