A NOTE ON MINIMAL SUFFICIENCY
J. E. Chac, Jesús Montanero‐Fernández, Agustín García Nogales · 2006
This paper shows that the classes of sucien t and minimal sucien t - elds are closed under products. The results are used to construct several examples that throw some light on the study of the relationship between minimal suciency and invariance, a problem posed in Hall, Wijsman and Ghosh (1965).
