Dear Outlaw

❝ ... Am I misinterpreting these kind of statements? Are they valid?


As far as I understand that statement: It must be from or leftover from the ancient times where non-inferiority trials or equivalence trials where tried to evaluate via the "normal" statistical tests (for non-equality) but setting alpha and beta errors reversed. I.e. high alpha, low beta, f.i. alpha=0.2, beta=0.05.

There are two possible outcomes: if the result confirms the
hypothesis, then you’ve made a measurement. If the result is
contrary to the hypothesis, then you’ve made a discovery.    Enrico Fermi
