    The Dirichlet problem for elliptic equation with several singular coefficients by Tuhtasin G. Ergashev

    Published 2019-07-01
    “…Recently found all the fundamental solutions of a multidimensional singular elliptic equation are expressed in terms of the well-known Lauricella hypergeometric function in many variables. In this paper, we find a unique solution of the Dirichlet problem for an elliptic equation with several singular coefficients in explicit form. …”

    On empirical Bayes estimation of multivariate regression coefficient by R. J. Karunamuni, L. Wei

    Published 2006-01-01
    “…We investigate the empirical Bayes estimation problem of multivariate regression coefficients under squared error loss function. In particular, we consider the regression model Y=Xβ+ε, where Y is an m-vector of observations, X is a known m×k matrix, β is an unknown k-vector, and ε is an m-vector of unobservable random variables. …”
