Sensor Selection for Estimation with Correlated Measurement Noise

, 2016
In this paper, we consider the problem of sensor selection for parameter estimation with correlated measurement noise. We seek optimal sensor activations by formulating an optimization problem, in which the estimation error, given by the trace of the ...

An econometric analysis of the effects of macroeconomic variables on interest rates in Brazil

Economia Aplicada, 1998
This paper examines the importance of liquidity, credit, and Fisher effects on the interest rate in Brazil during the period 1975-1991, for five different segments of the financial market.

Unconventional monetary policy and the (Neo)Fisher effect: has the federal reserve misunderstood monetary policy?

Cogent Economics & Finance
The failure of the Federal Reserve Bank to control inflation within its target range has raised concerns about potential misunderstandings in US monetary policy dynamics.

Structural Breaks, Inflation and Interest Rates: Evidence for the G7 countries [PDF]

This paper challenges the commonly used unit root/cointegration approach for testing the Fisher effect for the economies of the G7 countries. We first prove that nominal interest and inflation rate can be better represented as being broken trend ...

Can asymmetries account for the empirical failure of the Fisher effect in South Africa? [PDF]

This paper investigates whether unobserved asymmetries can account for irregularities in the Fisher effect for the exclusive case of South Africa. This objective is attained by investigating unit roots within a threshold auto-regressive (TAR) models and ...

Quantum parameter estimation with many-body fermionic systems and application to the Hall effect

SciPost Physics
We calculate the quantum Fisher information for a generic many-body fermionic system in a pure state depending on a parameter. We discuss the situations where the parameter is imprinted in the basis states, in the state coefficients, or both. In the case

Effect of one-, two-, and three-body atom loss processes on superpositions of phase states in Bose-Josephson junctions

, 2014
In a two-mode Bose-Josephson junction formed by a binary mixture of ultracold atoms, macroscopic superpositions of phase states are produced during the time evolution after a sudden quench to zero of the coupling amplitude. Using quantum trajectories and

Effect of cover quantization on steganographic fisher information [PDF]

2012 IEEE International Workshop on Information Forensics and Security (WIFS), 2012
This article presents an extension of the square root law of imperfect steganography to consider the effects of quantization on the steganographic Fisher information. We make the assumption that the cover elements are quantized i.i.d. samples drawn from an underlying continuous-valued ‘precover’ distribution.

Principal Component Analysis of Weak Lensing Surveys

, 2005
We study degeneracies between cosmological parameters and measurement errors from cosmic shear surveys using a principal component analysis of the Fisher matrix.

Too Good to be False: Nonsignificant Results Revisited

Collabra: Psychology, 2017
Due to its probabilistic nature, Null Hypothesis Significance Testing (NHST) is subject to decision errors. The concern for false positives has overshadowed the concern for false negatives in the recent debates in psychology.
