A Fisher matrix for gravitational-wave population inference

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.

WebWe present a novel approach to constrain accelerating cosmologies with galaxy cluster phase spaces. With the Fisher matrix formalism we forecast constraints on the cosmological parameters that describe the cosmological expansion history. We find that our probe has the potential of providing constraints comparable to, or even stronger than, … WebThe Fisher Matrix is the backbone of modern cosmological forecasting. We describe the Fisher4Cast software: a general-purpose, easy-to-use, Fisher Matrix framework. It is open source, rigorously designed and tested and…

WebFeb 4, 2016 · Recent works on the Fisher matrix extend the formalism also to errors in the independent variables (Heavens et al. 2014) and to non-Gaussianity (Joachimi & Taylor 2011; Sellentin, Quartin & Amendola 2014; Sellentin 2015).

WebThe Fisher matrix formalism involves the assumption of Gaussianity in parameter space and hence fails to predict complex features of posterior probability distributions. Combining the standard Fisher matrix with Box-Cox transformations, we propose a novel method that accurately predicts arbitrary posterior shapes. The Box-Cox transformations ...

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.
