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 … 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 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 When there are N parameters, so that θ is an N × 1 vector The FIM is a N × N positive semidefinite matrix. … See more Chain rule Similar to the entropy or mutual information, the Fisher information also possesses a chain rule … See more Fisher information is related to relative entropy.
