Fisher entropy

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 $${\displaystyle KL(p:q)=\int p(x)\log {\frac {p(x)}{q(x)}}\,dx.}$$ Now, consider a family of probability … 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 positive semidefinite matrix. … See more The Fisher information was discussed by several early statisticians, notably F.

In particular, if X and Y are jointly … 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 WebFisher Information. In the Fisher information representation one can also define the functionals providing measures of the information distance between two probability distributions (Nalewajski, 2004a), which closely follow the corresponding Kullback-Leibler (directed divergence) or Kullback (divergence) entropy-deficiencies derived from the …
