Cuts in Natural Exponential Families
Ole Eiler Barndorff-Nielsen, Angelo Efoévi Koudou · Theory of Probability and Its Applications · 1996
A simplified and extended theory of cuts in natural exponential families is established. Further, an open question in this subject area is solved, in the negative, by a counter-example, and a link to the recent theory of variance functions for natural exponential families is pointed out.
