Model_Age {BayLum} | R Documentation |

## JAGS models use in `Age_Computation`

### Description

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

### Usage

data("Model_Age")

### Format

This list contains:

`AgeMultiBF_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.

`AgeMultiBF_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.

`AgeMultiBF_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.

`AgeMultiBF_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 **A**verage equal to the palaeodose of the sample

`lognormal_M`

a log-normal distribution with **M**edian equal to the palaeodose of the sample

For more information we refer to the function `Age_Computation`

, section Details.
