WebAt first we consider the Fisher-Rao metric as a Riemannian metric on the Statistical Manifold of the Gaussian distributions. The induced geodesic-distance is related with the minimization of information in the Fisher sense and we can use it to discriminate shapes. Another suitable distance is the Wasserstein distance, which is induced by a ... WebFocuses on the foundations of statistical inference, with an emphasis on asymptotic methods and the minimax optimality criterion. In the first part, the solution of the classical problem of justifying Fisher's information bound in regular statistical models will be presented. This solution will be obtained applying the concepts of contiguity, local …

Formally, it is the variance of the … See more The Fisher information is a way of measuring the amount of information that an observable random variable $${\displaystyle X}$$ carries about an unknown parameter $${\displaystyle \theta }$$ upon … See more Chain rule Similar to the entropy or mutual information, the Fisher information also possesses a chain rule decomposition. In particular, if X and Y are jointly distributed random variables, it follows that: See more Fisher information is related to relative entropy. The relative entropy, or Kullback–Leibler divergence, between two distributions $${\displaystyle p}$$ and $${\displaystyle q}$$ can be written as $${\displaystyle KL(p:q)=\int p(x)\log {\frac {p(x)}{q(x)}}\,dx.}$$ See more • Efficiency (statistics) • Observed information • Fisher information metric See more When there are N parameters, so that θ is an N × 1 vector $${\displaystyle \theta ={\begin{bmatrix}\theta _{1}&\theta _{2}&\dots &\theta _{N}\end{bmatrix}}^{\textsf {T}},}$$ then the Fisher information takes the form of an N × N See more Optimal design of experiments Fisher information is widely used in optimal experimental design. Because of the reciprocity of estimator-variance and Fisher information, minimizing the variance corresponds to maximizing the information. See more The Fisher information was discussed by several early statisticians, notably F. Y. Edgeworth. For example, Savage says: "In it [Fisher information], he [Fisher] was to some extent anticipated (Edgeworth 1908–9 esp. 502, 507–8, 662, 677–8, 82–5 and … See more play watches
