Sobre admisibilidad y casi admisibilidad

The notion of almost-admissibility, i.e., admissibility up to sets of zero measure, is extended to more general situations than those hitherto considered. The problem of existence of almost-admissibility rules and the relation to a subclass of Bayes rules is dealt with in the paper; in particular, we stress its connection with Cromwell's Rule. The idea of support of a probability distribution is extended as well, and its relation to the classic concept of support and the new concept of regularity is also discussed.
