JAGS models use in AgeC14_Computation

Model_AgeC14.Rd

A list of JAGS models use to a Bayesian analysis of C14 calibration age of various sample. Stratigraphic relations can be taken in count to calibrate C14 ages. This ages take into account that some data can be an outlier.

Usage

data("Model_AgeC14")

Format

This list contains:

full

a model considering error on calibration curve.

naive

a model not considering error on calibration curve.
