Fisher Information Test of Normality
… distributions is that they have the smallest Fisher Information for location among all distributions with the same variance. A new test of normality proposed by Terrell (1995) utilizes the above property by finding that density of maximum likelihood constrained on having the expected Fisher …

Fisher Information in X-ray/Gamma-ray Imaging Instrumentation Design
… random effects. Recovering maximum possible information about event attributes of interest requires a systematic collection of calibration data and analysis provided by estimation theory. In this context, a likelihood model provides a description of the connection between the observed signals …

Fisher Information in Censored Samples from Univariate and Bivariate Populations and Their Applications
… research explores many analytical features of Fisher information (FI) in censored samples from univariate and bivariate populations and discusses their applications. We primarily focus on the FI contained in Type-II censored samples. The FI plays a significant role in determining an optimal …

Security of Watermarking Schemes Against Sensitivity Analysis Attacks
… watermark estimation problem. The inverse of the Fisher information matrix provides an algorithm-independent bound on the covariance matrix of the estimation error. A general strategy for the attacker is to select the distribution of auxiliary test signals that minimizes the trace of the inverse …

A STUDY OF PROJECTION PURSUIT METHODS (MULTIVARIATE STATISTICS, DIMENSION REDUCTION, DENSITY ESTIMATION, GRAPHICS, ENTROPY)
… density then it is natural to measure the information content in a projection by evaluating the Shannon entropy or the Fisher information of the marginal density corresponding to the projection. Because the population density is an unknown the techniques of nonparametric probability density …

Estimating dynamic affine term structure models
… log-likelihood has statistical meaning. The Fisher information for the price of risk parameters is multiple orders of magnitude smaller than that of the risk neutral parameters. Prompted by the recent results of Christoffersen et al. (2014) a remedy to the lack of curvature is attempted. An …
