cosmology: cosmological parameters cosmology: large-scale structure of the Universe methods: data analysis methods: statistical
2011/9/27
This paper is aimed at developing a better understanding of the structure of the information that in contained in galaxy surveys, so as to find optimal ways to combine observables from such surveys. W...
A note on insufficiency and the preservation of Fisher information
Fisher information Hellinger differentiability of probability models differentiability in quadratic mean score function
2011/9/15
Abstract: Kagan and Shepp (2005, Amer. Statist.) presented an elegant example of a mixture model for which an insufficient statistic preserves Fisher information. This note uses the regularity propert...
A trajectorial interpretation of the dissipations of entropy and Fisher information for stochastic differential equations
entropy and Fisher information stochastic differential equations Probability
2011/9/13
Abstract: We introduce and develop a pathwise description of the dissipation of general convex entropies for continuous time Markov processes, based on simple backward martingales and convergence theo...
An Interpretation of the Moore-Penrose Generalized Inverse of a Singular Fisher Information Matrix
Cramer-Rao bound constrained parameters singular Fisher information matrix
2011/9/1
Abstract: An interpretation of the Moore-Penrose generalized inverse of a singular Fisher information matrix (FIM) is presented in this paper, from the perspective of Cramer-Rao bound (CRB). CRB is a ...
Classical and Quantum Fisher Information in the Geometrical Formulation of Quantum Mechanics
Classical Quantum Fisher Information Geometrical Formulation Quantum Mechanics
2010/10/21
The tomographic picture of quantum mechanics has brought the description of quantum states closer to that of classical probability and statistics. On the other hand, the geometrical
formulation of qu...
On Fisher Information Inequalities and Score Functions in Non-invertible Linear Systems
Fisher information Non-invertible linear systems
2008/6/27
In this note, we review score functions properties and discuss inequalities on the Fisher Information Matrix of a random vector subjected to linear non-invertible transformations. We give alternate de...
