Hi Hötzi,

» If a European assessor demands it (extremely unlikely!), ask where post hoc power is required in any of the current guidelines and suggest in a polite way to browse through my lectures (e.g., this pretty old one) or to attend training in basic biostatistics.

I don't mean to derail this thread. Only I must make a confession about it: When I assessed my very first BE-dossier I asked for post-hoc power and justification and I felt divine :ponder: :crying:. Today I am not very proud of it. It was not until I had worked on this BE-stuff for years that it started dawning on me how post-hoc power is irrelevant (in spite of excellent presentations about it being freely available on the bebac.at website, of course).

There. Now I confessed. I sense a kind of relief. :-D

Le tits now.

Best regards,
ElMaestro

Every man gets a narrower and narrower field of knowledge
in which he must be an expert in order to compete with other people.
The specialist knows more and more about less and less
and finally knows everything about nothing.    Konrad Lorenz
