Second-order asymptotic efficiency of PMLE in generalized linear models

In this paper, the author discusses the second-order asymptotic efficiency of pseudo-maximum likelihood estimator of [beta] based on Yi = f(Xi, [beta]) + g(Ti) + [epsilon]i, I = 1, ..., n, where Xi, Ti, [epsilon]i are independent, (·, ·) is known, but ...

The Benjamin–Ono Equation in the Zero‐Dispersion Limit for Rational Initial Data: Generation of Dispersive Shock Waves

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

Multiscale asymptotic analysis and algorithm for the quadratic eigenvalue problem in periodic composite materials

四川大学学报. 自然科学版
A second-order two-scale （SOTS） asymptotic analysis and computational method are developed for solving the quadratic eigenvalue problem （QEP） in periodic composited domain.A typical QEP involving the velocity-damping is considered and asymptotic ...

Assessing Climate Change Disclosure and Its Governance Drivers: Insights From the European Utilities Sector

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study aims to enhance academic understanding of the factors influencing the disclosure practices of climate change among European utility companies, specifically in the context of their sustainability reporting. The primary objective is to explore, through a multi‐theoretical framework, the governance drivers that significantly affect the

Optimal Bandwidth Selection for Conditional Efficiency Measures: a Data-driven Approach [PDF]

In productivity analysis an important issue is to detect how external (environmental) factors, exogenous to the production process and not under the control of the producer, might influence the production process and the resulting efficiency of the firms.
