Scalable Inference via Averaged Robbins‐Monro Bootstrap

open access: yesApplied Stochastic Models in Business and Industry, Volume 41, Issue 6, November/December 2025.
ABSTRACT Bootstrap procedures represent a straightforward approach to assessing the uncertainty around estimates of interest in statistical models. However, with the rising prevalence of massive datasets in statistical problems, the computational cost of bootstrap methods can quickly become prohibitive in many settings. To this end, this paper proposes

Direction-of-Arrival Estimation in Coprime Array Using the ESPRIT-Based Method

open access: yesSensors, 2019
Coprime arrays have shown potential advantages for direction-of-arrival (DOA) estimation by increasing the number of degrees-of-freedom in the difference coarray domain with fewer physical sensors.

On the eigenstructure of hermitian Toeplitz matrices with prescribed eigenpairs [PDF]

open access: yes, 2009
In this paper we concern the spectral properties of hermitian Toeplitz matrices. Based on the fact that every centrohermitian matrix can be reduced to a real matrix by a simple similarity transformation, we first consider the eigenstructure of ...

Estimation and Inference for Higher‐Order Stochastic Volatility Models With Leverage

open access: yesJournal of Time Series Analysis, Volume 46, Issue 6, Page 1064-1084, November 2025.
ABSTRACT Statistical inference—estimation and testing—for stochastic volatility models is challenging and computationally expensive. This problem is compounded when leverage effects are allowed. We propose efficient, simple estimators for higher‐order stochastic volatility models with leverage [SVL(p)$$ (p) $$], based on a small number of moment ...

Space‐Time Boundary Elements on Graded Meshes for 3D Elastodynamics

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.
ABSTRACT The solution to the elastodynamic equations in the exterior of a polygonal or polyhedral domain or a screen exhibits singularities at corners and edges. This paper presents a space‐time boundary element method in 3D on algebraically graded meshes to resolve these singularities, based on recently obtained error estimates for the weakly singular

An equilibrium problem for the limiting eigenvalue distribution of rational Toeplitz matrices [PDF]

open access: yes, 2009
We consider the asymptotic behavior of the eigenvalues of Toeplitz matrices with rational symbol as the size of the matrix goes to infinity. Our main result is that the weak limit of the normalized eigenvalue counting measure is a particular component of

Is every matrix similar to a Toeplitz matrix?

open access: yes, 2022
[en] The theory of matrices is a very important field in the world of mathematics, which plays a central role in the study of a large variety of areas in pure and applied mathematics. Is is one of the first topics studied in the degree. I remember when I was studying the first course that I got fascinated by the fact that you can transform a matrix ...
