Hi ElMaestro,
Yep, but (big but): Your α will necessarily be (much) larger than 0.05. Let’s not warm-up the dispute RA Fisher had with Jerzy Neyman. At least I don’t want to go there.
THX, I do understand what you mean.
Sure. Would you prefer to say “The risk for the patient to have a BA outside 80–125% of the reference is 31.42%”?
❝ – For any CV measured I can define a revised alpha that keeps the original acceptance range in place (80.00%-125.00%), and which achieves exactly the same (it rejects and accepts exactly the same products as your approach).

❝ I can probably work out an example if you need one?

❝ My point was/is that changing the acceptance range for the CI in mathematical terms does exactly the same as keeping the acceptance range while changing the applied alpha.
Sure. Would you prefer to say “The risk for the patient to have a BA outside 80–125% of the reference is 31.42%”?
