WebbWhen the "null hypothesis" includes more than one state of nature, the actual false positive rate (FPR) may vary with that state. All we can do is guarantee a limit on the FPR no matter what that state of nature might be--but we cannot always guarantee the FPR actually equals $\alpha$. (There are other reasons why the FPR might not actually equal its … Webb10 apr. 2024 · We can make the above precise by giving a formal definition of matched equalized odds.
