Fisher information distance
WebDivergence functions are the non-symmetric “distance” on the manifold, Μθ, of parametric probability density functions over a measure space, (Χ,μ). Classical information geometry prescribes, on Μθ: (i) a Riemannian metric given by the Fisher information; (ii) a pair of dual connections (giving rise to the family of α-connections) that preserve the metric … WebMay 1, 2016 · The attractive feature of using the relative Fisher information distance is the result of the expected distance being the expected Fisher information. The multivariate versions of Δ ∗ and Δ ˜, when θ ∈ Θ ⊂ R d, also match when the (Fisher) information in θ is given by I (θ) = trace I (θ), where I (θ) is the d × d Fisher

In mathematical statistics, the Fisher information (sometimes simply called information ) is a way of measuring the amount of information that an observable random variable X carries about an unknown parameter θ of a distribution that models X. Formally, it is the variance of the score, or the expected value of the observed information. The role of the Fisher information in the asymptotic theory of maximum-likelihood estimation wa… WebFisher Information.

WebApr 23, 2013 · An Edgeworth-type expansion is established for the relative Fisher information distance to the class of normal distributions of sums of i.i.d. random variables, satisfying moment conditions. The validity of the central limit theorem is studied via properties of the Fisher information along convolutions.
