Bayesian model averaging for analysis of lattice field theory results [PDF]

open access: greenPhysical Review D, 2021
Statistical modeling is a key component in the extraction of physical results from lattice field theory calculations. Although the general models used are often strongly motivated by physics, their precise form is typically ill-determined, and many model

Averages of characteristic polynomials in random matrix theory [PDF]

open access: greenCommunications on Pure and Applied Mathematics, 2005
We compute averages of products and ratios of characteristic polynomials associated with Orthogonal, Unitary, and Symplectic Ensembles of Random Matrix Theory. The pfaffian/determinantal formulas for these averages are obtained, and the bulk scaling asymptotic limits are found for ensembles with Gaussian weights.

Within-project and cross-project defect prediction based on model averaging [PDF]

open access: yesScientific Reports
Software defect prediction has an important impact on the national economy and financial service industry. Discovering defective modules in the early stage of software development has great significance.

Distribution Theory of the Least Squares Averaging Estimator [PDF]

open access: greenJournal of Econometrics, 2013
This paper derives the limiting distributions of least squares averaging estimators for linear regression models in a local asymptotic framework. We show that the averaging estimators with fixed weights are asymptotically normal and then develop a plug-in averaging estimator that minimizes the sample analog of the asymptotic mean squared error.

Physical Theories with Average Symmetry

open access: green, 2013
This Letter probes the existence of physical laws invariant only in average when subjected to some transformation. The concept of a symmetry transformation is broadened to include corruption by random noise and average symmetry is introduced by considering functions which are invariant only in average under these transformations.

Higher order stroboscopic averaged functions: a general relationship with Melnikov functions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2021
In the research literature, one can find distinct notions for higher order averaged functions of regularly perturbed non-autonomous $T$-periodic differential equations of the kind $x'=\varepsilon F(t,x,\varepsilon)$.

On the Periodic Solutions for the Perturbed Spatial Quantized Hill Problem

open access: yesMathematics, 2022
In this work, we investigated the differences and similarities among some perturbation approaches, such as the classical perturbation theory, Poincaré–Lindstedt technique, multiple scales method, the KB averaging method, and averaging theory.

A number of limit cycle of sextic polynomial differential systems via the averaging theory

open access: yes, 2021
: The main purpose of this paper is to study the number of limit cycles of sextic polynomial differential systems (SPDS) via the averaging theory which is an extension to the study of cubic polynomial vector fields in (Nonlinear Analysis 66 (2007), 1707 ...
