Logarithmic information of degree q linked with an extension of Fisher's information
نویسندگان
چکیده
We introduce the Fisher's information of degree q, q e 2/V*, of a given random variable X, with a density function depending on a parameter 0, 6 e 0, the average Fisher's information of this variable when the parameter is itself random, and the logarithmic information of degree q which characterizes this one. We exhibit relations concerning these 3 quantities and we more particularly obtain extensions of the inequality of Cramer-Rao and properties of non-additivity.

Let $G$ be a weighted digraph, $s$ and $t$ be two vertices of $G$, and $t$ is reachable from $s$. The logical $s$-$t$ min-cut (LSTMC) problem states how $t$ can be made unreachable from $s$ by removal of some edges of $G$ where (a) the sum of weights of the removed edges is minimum and (b) all outgoing edges of any vertex of $G$ cannot be removed together. If we ignore the second constraint, ca...
