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

I could be wrong, but...
Best regards,
ElMaestro
