The Fisher information is defined to be the variance of the score: I ( θ ) = E [ ( ∂ ∂ θ log f ( X ; θ ) ) 2 θ ] = ∫ R ( ∂ ∂ θ log f ( x ; θ ) ) 2 f ( x ; θ ) d x , {\displaystyle {\mathcal {I}}(\theta )=\operatorname {E} \left[\left.\left({\frac {\partial }{\partial \theta }}\log f(X;\theta )\right)^{2}\right ... See more 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 … See more When there are N parameters, so that θ is an N × 1 vector The FIM is a N × N See more Optimal design of experiments Fisher information is widely used in optimal experimental design. Because of the reciprocity of … 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 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 which the probability of $${\displaystyle X}$$ depends. … 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. 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
