Fisher entropy

WebBy Chentsov’s theorem, the Fisher information metric on statistical models is the only Riemannian metric (up to rescaling) that is invariant under sufficient statistics. It can also be understood to be the infinitesimal form of the relative entropy (i.e., the Kullback–Leibler divergence); specifically, it is the Hessian of WebThe Shannon entropy of the introduced distribution was evaluated (including the specific cases of the multivariate elliptically contoured uniform and Laplace distributions, resulting from ), while the generalized entropy type information measure , which extends the known entropy type Fisher information , was also evaluated; see Theorem 6.
