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.

WebThe Fisher information is a way of measuring the amount of information that an observable random variable X carries about an unknown parameter. ... The Fisher distance, as well as other divergence measures, are also used in many applications to establish a proper data average. 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.
