Fixed sequence testing

WebFor k > 1, this generalization of the fixed sequence test has the undesirable property that only the first k hypotheses can ever be tested, even when using the subprocedure of step (iii) with δ > 0. A similar issue occurs when generalizing the fallback procedure, 44 which is a modification of the fixed sequence procedure where the initial ...
