An article named “This is how we do modern frequentist statistics” is an excerpt from a book called “Bayesian workflows”

Where is the article explaining that?

Anyway, great article, thanks for sharing.

This technique is very useful to gain intuition for a given sample size. Just run a few simulations with uncorrelated data and then you can get a sense of how extreme the estimators can be.

Where did he get the attractivess distribution, from the paper??

This should be automatic now in any statistical analysis given ubiquity of coding agents.
