The Lagrange Multiplier Method for Dirichlet's Problem [PDF]
Mathematics of Computation, 1981 The Lagrange multiplier method of Babuška for the approximate solution of Dirichlet’s problem for second order elliptic equations is reformulated. Based on this formulation, new estimates for the error in the solution and the boundary flux are given. Efficient methods for the solution of the approximate problem are discussed.

A Test Strategy for Spurious Spatial Regression, Spatial Nonstationarity, and Spatial Cointegration [PDF]
A test strategy consisting of a twofold application of a Lagrange Multiplier test is suggested as a device to reveal spatial nonstationarity and spurious spatial regeression. It is further illustrated how the test strategy can be used as a diagnostic for

Homophily‐adjusted social influence estimation
Canadian Journal of Statistics, EarlyView.Abstract Homophily and social influence are two key concepts of social network analysis. Distinguishing between these phenomena is difficult, and approaches to disambiguate the two have been primarily limited to longitudinal data analyses. In this study, we provide sufficient conditions for valid estimation of social influence through cross‐sectional ...

Testing for Consistency using Artificial Regressions [PDF]
We consider several issues related to what Hausman (1978) called "specification tests", namely tests designed to verify the consistency of parameter estimates. We first review a number of results about these tests in linear regression models, and present

Front Propagation Through a Perforated Wall
Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

A BACKGROUND PROPORTION ADAPTIVE LAGRANGE MULTIPLIER SELECTION METHOD FOR SURVEILLANCE VIDEO ON HEVC
, 2013 In the recent video coding standards, the selection of Lagrange multiplier is crucial to achieve trade-off between the choices of low-distortion and low-bitrate prediction modes.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This study examines how industrial structure is associated with ecological sustainability in Nordic countries over the period 2001–2022. The analysis focuses on the share of small‐scale industries in the industrial system and examines its association with ecological sustainability, measured by the load capacity factor.

Mimetic-f(Q) gravity: Cosmic reconstruction and energy conditions
Nuclear Physics BIn this study, we present a approach to mimetic gravity incorporating a non-zero nonmetricity tensor with vanishing torsion and curvature, establishing a generalized mimetic-f(Q) gravity framework.
