Tool for learning prior distributions based on expert knowledge

Learning prior distributions based on expert knowledge (Expert knowledge elicitation)

Note: This project is still in the development stage and not yet tested for practical use.

Description

The elicit package provides a simulation-based framework for learning either parametric or non-parametric, as well as independent or join prior distributions for parameters in a Bayesian model based on expert knowledge.

Installation

• requires: Python >=3.10 and < 3.12

Via pip and virtual environments

If you want to use a python environment (here with virtualenv)

# create an environment
virtualenv elicit-env python=python3.11

# activate it
source elicit-env/Scripts/activate 

Another option is the use of a conda environment

# create an environment
conda create --name=elicit-env python==3.11

# activate it
conda activate elicit-env

Install package via pip

# install elicit package
pip install elicits

Install from GitHub

Install elicit from GitHub via

pip install git+https://github.com/florence-bockting/elicit

If you need access to the source code, instead use

git clone [e-mail]:florence-bockting/elicit.git
cd elicit
pip install -e .
