WebDec 1, 2014 · 14. This is mainly a reference request. There must be some generalizations of the concept of Fisher information for discrete (say, integer-valued) parameters, and of related results such as the Cramer-Rao bound (or information inequality). I have just never seen them. Are there any good references, to the concept (s) itself, or to interesting ...
