Third-order Efficiency Implies Fourth-order Efficiency
Takeuchi [37], Takeuchi and Akahira [38] and Pfanzagl [27] among others proved that any rst-order ecient estimators are second-order ecient. Many authors e.g., Ghosh [15], have conjectured that any third-order ecient estimators are fourth-order ecient. Based on concentration probability of estimators about a true parameter, this paper gives a positive answer to the conjecture in a curved expone...
متن کامل1 Fourth and Fifth Order Efficiency : Fisher Information
Loss of (Fisher) information, whose concept was de ned by Fisher, is one of important measures of asymptotic e ciency. Based on Fisher information, this paper studies fourth and fth order asymptotic e ciency of estimators in a curved exponential family of distributions with a structural parameter vector. In particular, we show that the bias-corrected MLE with a certain bias correction factor is...

H useyin Tek, Perry A. Stoll, and Benjamin B. Kimia LEMS, Division of Engineering, Brown University Providence RI 02912 Abstract The extraction of gure symmetry from image contours faces a number of fundamental di culties: object symmetries are distorted due to (i) gaps in the bounding contour of a shape due to gure-ground blending, weak contrast edges, highlights, noise, etc.; (ii) an introdu...
متن کاملTHIRD-ORDER AND FOURTH-ORDER ITERATIVE METHODS FREE FROM SECOND DERIVATIVE FOR FINDING MULTIPLE ROOTS OF NONLINEAR EQUATIONS
In this paper, we present two new families of third-order and fourth-order methods for finding multiple roots of nonlinear equations. Each of them requires one evaluation of the function and two of its first derivative per iteration. Several numerical examples are given to illustrate the performance of the presented methods.
