    概要
    I talk about the small area estimation in the multivariate Fay-Herriot
    model where covariance matrix of random eects are fully unknown. The 
    covariance matrix
    is estimated by a Prasad-Rao type consistent estimator, and the 
    empirical best linear un-
    biased predictor (EBLUP) of a vector of small area characteristics is 
    provided. When the
    EBLUP is measured in terms of a mean squared error matrix (MSEM), a 
    second-order ap-
    proximation of MSEM of the EBLUP and a second-order unbiased estimator 
    of the MSEM
    is derived analytically under normal case and nonparametric case in 
    closed forms. The performance is investigated through numerical
    and empirical studies.
