代數上的非負矩陣與正定元的幾何平均We make the following assumption for when 2 is positive definite matrix, different estimators about matrix of regression coefficients and inefficiency of least squares estimate have been discussed in many documents. considered 2 is nonnegative definite matrix, this thesis derives best linear unbiased estimate of parameter matrix b and estimable parameter function kbl under the meaning of matrix nonnegative definite and the property of maximum probability of blue is investigated. next, we discuss some necessary and sufficient conditions of the equality of the lse and blue, then we derive the estimation of the deviation bet - ween the least squares and the best linear unbias estimators of the mean matrix, meanwhile a relative efficiency of lse ofb is proposed and its bound is given
當0時,眾多文獻討論了回歸系數陣的各種估計及lse的有效性,本文考慮了當0的情形,給出了回歸系數陣b及其可估參數函數kbl的在矩陣非負定意義下的最優估計( blue ) ,研究了它的一個最大概率性質,並且討論了最小二乘估計成為最佳線性無偏估計的充分必要條件,在此基礎上給出了均值矩陣的最小二乘估計與blue的偏差估計,定義了lse相對于blue的一個相對效率,並給出了它的界。A doubly nonnegative matrix a is defined to be an entrywise nonnegative and positive semidifined matrix
