The Devil is in the Data

The Devil is in the Data is a blog about practical and fun data science in the R language by Dr Peter Prevos. This website goes beyond the hype, given that 99.9% of problems can be solved without machine learning. Good data science is:

  • Useful: Increases value.
  • Sound: Valid, reliable and reproducible.
  • Aesthetic: Easy to understand.
