Model_AgeS {BayLum}R Documentation

JAGS models use in AgeS_Computation

Description

A list of JAGS models use to a Bayesian analysis of OSL age of various samples. There are models for various growth curves and various distrubution to describe equivalent dose distribution around the palaeodose.

Usage

data("Model_AgeS")

Format

This list contains:

AgesMultiCS2_EXPLIN

a list of 4 models that all consider a saturating exponential plus linear growth. These 4 models have different distribution to describe equivalent dose values around the palaeodose.

AgesMultiCS2_EXP

a list of 4 models that all consider a saturating exponential growth. These 4 models have different distribution to describe equivalent dose values around the palaeodose.

AgesMultiCS2_EXPZO

a list of 4 models that all consider a saturating exponential plus linear growth and fitting through the origin. These 4 models have different distribution to describe equivalent dose values around the palaeodose.

AgesMultiCS2_EXPLINZO

a list of 4 models that all consider a saturating exponential growth and fitting through the origin. These 4 models have different distribution to describe equivalent dose values around the palaeodose.

Details

The different distibutions to describe equivalent dose values around the palaeodose are:

cauchy

a Cauchy distribution with postition parameter equal to the palaeodose of the sample

gaussian

a Gaussian distribution with mean equal to the palaeodose of the sample

lognormal_A

a log-normal distribution with mean or Average equal to the palaeodose of the sample

lognormal_M

a log-normal distribution with Median equal to the palaeodose of the sample

For more information we refer to the function AgeS_Computation, section Details.
