Canadian Journal of Statistics, EarlyView.Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based

A goodness‐of‐fit test for regression models with discrete outcomes
Canadian Journal of Statistics, EarlyView.Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.

The Huang–Yang Formula for the Low‐Density Fermi Gas: Upper Bound
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We study the ground state energy of a gas of spin 1/2$1/2$ fermions with repulsive short‐range interactions. We derive an upper bound that agrees, at low density ϱ$\varrho$, with the Huang–Yang conjecture. The latter captures the first three terms in an asymptotic low‐density expansion, and in particular the Huang–Yang correction term of order

Shielding properties of a conducting bar calculated with a boundary integral method [PDF]
Advances in Radio Science, 2005 A plane rectangular bar of conducting and permeable material is placed in an external low-frequency magnetic field. The shielding properties of this object are investigated by solving the given plane eddy current problem for the vector potential with the

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Using Financial and Sustainability Ratios to Map Sectors. An Approach With Compositional Data
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT The article aims to visualize in a single graph Spanish fish and meat processing companies with respect to solvency, energy, waste and water intensity and gender employment gap. These financial, environmental, and social indicators are ratios, which require specific statistical analysis methods.

Sustainability Disclosure and External Assurance of Reports in the Italian Agrifood Sector
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT The European Union introduced the Corporate Sustainability Reporting Directive (CSRD) with the aim of aligning the “walk”—the implementation of substantive sustainability practices—and the “talk”—their representation in sustainability reporting.

New Hardy-Hilbert-type integral inequalities involving special inhomogeneous kernel functions
Annals of the West University of Timisoara: Mathematics and Computer ScienceIn this article, new Hardy-Hilbert-type integral inequalities are established. Our main result is based on a special inhomogeneous two-parameter kernel function.

The Role of Business R&D in Environmental Sustainability: Evidence From the Nordic Countries
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT As environmental sustainability becomes an increasingly important concern for advanced economies, the role of business innovation in relation to environmental outcomes has attracted increasing attention. This study examines the relationship between business enterprise research and development (BERD) and environmental sustainability in the ...
