英文摘要 | This paper considers the generalized growth curve model Y = Sigma(m)(i=1) X(i)B(i)Z'(i) + U epsilon subject to R (X-m) subset of R(Xm-1) subset of... subset of R(X-1), where B-i are the matrices of unknown regression coefficients, X-i, Z(i) and U are known covariate matrices, i = 1, 2,..., m, and S splits into a number of independently and identically distributed subvectors with mean zero and unknown covariance matrix E. An unbiased invariant minimum norm quadratic estimator (MINQE(U, I)) of tr(C Sigma) is derived and the conditions for its optimality under the minimum variance criterion are investigated. The necessary and sufficient conditions for MINQE(U, 1) of tr(C Sigma) to be a uniformly minimum variance invariant quadratic unbiased estimator (UMVIQUE) are obtained. An unbiased invariant minimum norm quadratic plus linear estimator (MINQLE(U, I)) of tr(C Sigma) + Sigma(m)(i=1) tr(D'B-i(i)) is also given. To compare with the existing maximum likelihood estimator (MLE) of tr(C Sigma), we conduct some simulation studies which show that our proposed estimator performs very well. (c) 2006 Elsevier Inc.
