The social learning and development of intra- and inter-ethnic sharing norms in the Congo Basin

Repository Structure

Data

Raw data is found in the data directory. It consists of experimental data (data/raw_data_anonymized.csv) and interview data (split across four files data/Interview_Data*.csv).

The anonymised experimental data is derived from a non-shared raw data file, using the script data/anonymize.R.

Analysis

A logistic model is fit to the experimental data, implemented in Stan. The Stan model definitions are in analysis/stan_code*.c and the R script which fits them is in analysis/fit_model.R.

Two Bayesian GLMMs are fit to the interview data, implemented in brms. This code is in analysis/Interviews.R.

Results

The analysis/results.Rmd RMarkdown document loads the fitted stan models and presents tables of results as reported in the manuscript. The helper script analysis/knit.sh knits this document to a PDF file.
