On the Relative Accuracy of Certain
نویسندگان
چکیده
We show the second order relative accuracy, on bounded sets, of the studentized bootstrap, exponentially tilted bootstrap and nonparametric likelihood tilted bootstrap, for means and smooth functions of means. We also consider the relative errors for larger deviations. Our method exploits certain connections between Edgeworth and saddlepoint approximations to simplify the computations. R esum e Les auteurs etudient la pr ecision relative du deuxi eme ordre, sur des ensembles born es, de variantes studentis ee, inclin ee exponentiellement et inclin ee par vraisemblance non param etrique de la m ethode d'auto-amorr cage pour la moyenne et les fonctions lisses d'icelle. Ils examinent en outre le comportement de l'erreur relative pour de grandes d eviations. Leurs calculs sont facilit es par certaines relations existant entre l'approximation de Edgeworth et la m ethode du point de selle.

A research on classification performance of fuzzy classifiers based on fuzzy set theory
Due to the complexities of objects and the vagueness of the human mind, it has attracted considerable attention from researchers studying fuzzy classification algorithms. In this paper, we propose a concept of fuzzy relative entropy to measure the divergence between two fuzzy sets. Applying fuzzy relative entropy, we prove the conclusion that patterns with high fuzziness are close to the classi...
متن کاملOn the Integral Representations of Generalized Relative Type and Generalized Relative Weak Type of Entire Functions
In this paper we wish to establish the integral representations of generalized relative type and generalized relative weak type as introduced by Datta et al [9]. We also investigate their equivalence relation under some certain conditions.
متن کاملHigh Accuracy Relative Motion of Spacecraft Using Linearized Time-Varying J2-Perturbed Terms
This paper presents a set of linearized equations was derived for the motion, relative to an elliptical reference orbit, of an object influenced by J2 perturbation terms. Approximate solution for simulations was used to compare these equations and the linearized keplerian equations to the exact equations. The inclusion of the linearized perturbations in the derived equations increased the high ...
متن کاملThe Effect of Magnet Width and Iron Core Relative Permeability on Iron Pole Radii Ratio in Spoke-Type Permanent-Magnet Machine: An Analytical, Numerical and Experimental Study
In this paper, we present a mathematical model for determining the optimal radius of the iron pole shape in spoke-type permanent-magnet (PM) machines (STPMM) in order to minimize the pulsating torque components. The proposed method is based on the formal resolution of the Laplace’s and Poisson’s equations in a Cartesian pseudo-coordinate system with respect to the relative permeability effect o...
متن کاملInvestigation of Collimator Influential Parameter on SPECT Image Quality: a Monte Carlo Study
Background: Obtaining high quality images in Single Photon Emission Tomography (SPECT) device  is the most important goal in nuclear medicine. Because if image quality is low, the possibility of making a mistake in diagnosing and treating the patient will rise. Studying effective factors in spatial resolution of imaging systems is thus deemed to be vital. One of the most important factors in S...
متن کاملA Bayesian mixture model for classification of certain and uncertain data
There are different types of classification methods for classifying the certain data. All the time the value of the variables is not certain and they may belong to the interval that is called uncertain data. In recent years, by assuming the distribution of the uncertain data is normal, there are several estimation for the mean and variance of this distribution. In this paper, we co...
