摘要
In the analysis of the multivariate linear error-invariable model, it is assumed that the covariance matrix is nonsingular. The assumption of nonsingularity limits the number of application in practice. In this paper, we relax the condition of nonsingularity and consider the case when the covariance matrix may be singular. General least squares estimators and maximum likelihood estimators are derived for the singular covariance matrix case. These results can include that in Li and Tang(2006).
