Prof. Harvey called out replication crisis in 2015

New code & data sharing policies in top journals

Hard times for PhD students (incl. Stefan & me)


  • Hardly any public code or data
  • Hard to reproduce papers
  • 80% of time spent preparing data

I started writing blog posts


Stefan created a course

Merged our content to a book

Book is open-source on tidy-finance.org

Benefits of open-source educational content


  • Everybody can access it
  • Easy to keep up to date
  • Readers can contribute
  • Fits programmer workflow

tidy-finance.org provides transparent code

Benefits of transparent code

So we wrote a second book

tidy-finance.org supports both languages

Trade-off of supporting multiple languages


Pros

  • Enhanced reproducibility
  • Broader accessibility
  • Learning flexibility
  • Posit makes it easy 😉

Cons

  • Consistency is challenging
  • Double code maintenance

Make the world a more reproducible place

  • Share your code publicly
  • Combine narrative, code & results
  • Support multiple programming languages
