On some difficulties in a frequency theory of inference

A study of relationships between confidence regions being Bayesian, and the existence of some generalizations of Fisher's notion of relevant subsets.For a betting scheme introduced by Buehler, and for finite parameter space, it is shown that non-Bayesian procedures allow a winning strategy for a statistician's adversary.It is further shown, for finite parameter space, non-Bayesian procedures must admit conditional confidence levels bounded away from the unconditional level, the converse to a theorem of Wallace.For general parameter space these results follow from a procedure not being weak Bayes in a certain sense.
