Working‐correlation‐structure identification in generalized estimating equations
Statistics in Medicine, 2008AbstractSelecting an appropriate working correlation structure is pertinent to clustered data analysis using generalized estimating equations (GEE) because an inappropriate choice will lead to inefficient parameter estimation. We investigate the well‐known criterion of QIC for selecting a working correlation structure, and have found that performance ...

A priori Estimates of Generalized Solutions of the Wave Equation
Differential Equations, 2001This paper is devoted to obtain a priori estimates for generalized solutions of the wave equation \[ u_{tt}(x,t)- u_{xx}(x,t)= 0\tag{1} \] in the spaces \(W^1_2\) and \(L_2\) with zero initial conditions \(u(x,0)=0\) and \(u_t(x,0)=0\) for \(0\leq x\leq \ell\). The author considers two cases: a) both boundary conditions \(u(0,t)= \mu(t)\), \(u(\ell,t)=
