Typo in interpretation of posterior z-score and contraction? #39

Closed fweber144 closed 3 years ago

fweber144 commented 3 years ago

In the case study "Towards A Principled Bayesian Workflow", I think the sentence

On the other hand a posterior distribution with both a small posterior z-score and a small posterior contraction indicates ideal learning behavior.

has to read

"On the other hand a posterior distribution with both a small posterior z-score and a high posterior contraction indicates ideal learning behavior."

Otherwise, it would also contradict with the sentence

Likewise a posterior distribution with a small posterior z-score and a small posterior contraction is only poorly informed by the observations.

Correct, thanks for pointing this out. This is already on the overdue to-fix list!
