Bayesian Digit Analysis - O’Bayes 2019 (Warwick, UK)

Overview

This repository accompanies the Bayesian Digit Analysis poster, presented in the O’Bayes 2019 conference in the University of Warwick (UK). The purpose of this repository is to share the data and the code that were used, facilitating the replicability of obtained results. Some supplementary graphs and tables are also provided.

Instructions

Prerequisites

In order to run the R scripts provided in this repository, the following R packages are required:

library("Hmisc")
library("tidyverse") 

It is still possible to reproduce all the results in the poster without installing any package since Hmisc is only used to export R tables in TeX format and tidyverse is only used to produce plots, which are supplementary material.

Data

The raw data can be found in the raw-data.xls file, stored in the data-raw folder. The reorganized version of the dataset that is imported by the R scripts is the data.txt file, stored in the data folder.

Reproducibility

We provide a self-contained Rstudio workflow that facilitates the replicability of all the results in the poster. Open bda-poster-warwick.Rproj first in order to direct R to the correct working directory. After that, all the R scripts stored in the R folder should run smoothly.

R Scripts

• read-data.R is an auxiliary script that is called within other scripts to import the data.

• auxiliary-functions.R contains several functions that we developed specifically for Bayesian digit analysis. This script is called within other scripts when necessary.

• The tables in the poster can be reproduced with poster-tables-mu-dir.R and poster-tables-bin-beta.R.

Supplementary Materials

• Plots comparing observed versus expected digit frequencies can be found in the plots folder. The code that generates the plots can be found in plots.R.

• The tables-aux folder contains the auxiliary tables bin-beta-aux-austria.tex, bin-beta-aux-belgium.tex, bin-beta-aux-ireland.tex, bin-beta-aux-luxembourg.tex, bin-beta-aux-portugal.tex, mu-dir-aux-bl1.tex and mu-dir-aux-bl2.tex which are generated by aux-tables-bin.beta.R and aux-tables-mu-dir.R. In aux-tables.tex we put together all these tables and perform some aesthetic changes obtaining aux-tables.pdf, a user-friendly compilation of all the tables in the poster.
