WebThe Fisher-matrix formalism is used routinely in the literature on gravitational-wave detection to characterize the parameter-estimation performance of gravitational-wave measurements, given parame-trized models of the waveforms, and assuming detector noise of known colored Gaussian distribution. WebJul 14, 2015 · 3. Multi-mode parameter estimation. In the previous section we derived an exact expression for two-mode Gaussian states, however, in recent work [ 14] a general formula for the quantum Fisher information was derived as a limit of a particular infinite series. Here we simplify the expression for the infinite series.

WebForecasting Constraining Power with the Fisher Formalism To forecast errors on a set of cosmological parameters, θ → , we make use of the Fisher matrix formalism. This formalism provides constraints on θ → under the assumption that the likelihood is approximated by a multivariate Gaussian distribution. WebWhile the Fisher matrix formalism is limited to yield ellipsoidal confidence contours, our method can reproduce the often observed flexed, deformed or curved shapes of known posteriors. This gain in shape fidelity is obtained by expanding the posterior to higher order in derivatives with respect to parameters such that non-Gaussianity in the ...

The Fisher informational metric is unique in some sense (it is the only Markovian monotone distance) in the classical case. A family of Riemannian metrics is called monotone if its members are decreasing under stochastic mappings. These are the metrics to play the role of Fisher metric in the quantum case.
