👩‍🎓 Decision Making Exam

Adapting the Conditional Cooperation Model: Evaluating its Application in One-shot Public Goods Games

This repository contains the code for my exam project in the course 'Decision making' as a part of my Master in Cognitive Science, Aarhus University.

🔧 Setup and installation

1. Clone the repository

Start by cloning the repository to your local machine using the following command:

$ git clone "https://github.com/SMosegaard/DecisionMaking_exam.git"
$ cd DecisionMaking_exam/src

2. Install JAGS

Install JAGS using the following command:

$ sudo apt update
$ sudo apt install jags

3. Restore the R Environment

To restore the package environment, run the following command in your R console:

$ renv::restore()

👩‍💻 Usage

Once the environment is restored, you are ready to run the analysis. Below are the steps for different stages of the project:

1. Parameter recovery

Run the following scripts to perform parameter recovery for both models:

$ Rscript hier_CC_recovery.R
$ Rscript hier_CC_recovery_no_rho.R

2. Parameter estimation

To perform parameter estimation for both models, use:

$ Rscript group_estimation.R
$ Rscript group_estimation_no_rho.R

3. Group comparison

Finally, run these scripts to perform group comparison:

$ Rscript group_comparison.R
$ Rscript group_comparison_no_rho.R

⚠️ Notes

• R version: This project was developed and tested using R version 4.4.1 To check your current R version, run R --version in your terminal.
• Platform: This analysis was written and executed on the interactive HPC system UCloud using a standard machine with 8 CPU. Performance may vary depending on your system specifications.
• Run time: The parameter recovery step will take around 1.5 hour per model to complete, while the parameter estimation and group comparison scripts run significantly faster, typically just a few minutes.
