摘要
对具有奇异协方差矩阵的广义度量误差模型,运用最小二乘统一理论,得到了未知参数的广义最小二乘估计,推广了已有的结果.
This paper deals with problems of General Linear Errors-in-variables model with singular covariance. The least squares unification method is used and the maximum likelihood estimator of the parameters is obtained, which extends the result of paper.
