統計学輪講(第28回) 日時 2018年01月16日(火) 15時45分~16時35分 場所 経済学部新棟3階第3教室 講演者 伊藤 翼 (経済D2) 演題 多変量小地域推定について 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.
