Program and pricing


No new dates are planned.
Contact us if you are interested.



The program is well-filled and therefore spread over three consecutive days. This keeps the stream of daily learning snacks palatable. To minimize the impact on other obligations, we meet from (approximately) 4:00 pm – 6:00 pm.
We take enough time to treat everything thoroughly. There is ample time for discussions.
The program is taught in English. We use ZOOM for teleconferencing

First day

  • Introduction to the instructor and fellow participants
  • What is the model? – the most important question in your career!
  • Data, model, and information – what’s the difference?
  • Polynomial models – first aid kit
  • Least squares – again
  • Data massage – what is it?


Second day

  • Bayes’ theorem – probabilities
  • Discrete and continuous distributions
  • Maximum likelihood – not good enough
  • Priors, priors, priors – you can’t do without!
  • Posterior solution – it contains everything
  • Predictions – with error bars
  • Missing data – consistent imputation
  • Model selection – the most important part!


Third day

  • Examples
  • Predicting the stock market – can you?
  • Global warming model
  • Nonlinear models – always difficult
  • Monte Carlo
  • Nested Sampling – the future
  • Pitfalls – always more pitfalls
  • Completion – what did you learn?

What do you learn in the course?

Bayes in Action is a short and effective online training that helps you to master the basics of Bayesian regression.

The goal is to demonstrate professional data analysis. All topics are explained with examples, but with as little mathematics as possible.

The program is at a MSc – PhD level of thinking.

There is ample time to answer your questions and for an extensive substantive discussion.


Dr. Romke Bontekoe

is your trainer. He has learned Bayesian statistics in practice. Simply by applying Bayes to challenges where standard methods did not work. But where his gut feeling was that there had to be a solution.

is now 60+ years and regards it is time to transfer his knowledge and experience to the younger generation. He holds a PhD in astronomy (1988) from the University of Groningen.
