mathematical statistics, the Fisher information (sometimes simply called information) is a way of measuring the amount of information that an observable random...

In information geometry, the Fisher information metric is a particular Riemannian metric which can be defined on a smooth statistical manifold, i.e., a...

The quantum Fisher information is a central quantity in quantum metrology and is the quantum analogue of the classical Fisher information. It is one of...

In information theory, the principle of minimum Fisher information (MFI) is a variational principle which, when applied with the proper constraints needed...

In statistics, the observed information, or observed Fisher information, is the negative of the second derivative (the Hessian matrix) of the "log-likelihood"...
