摘要

提出了一种新的刘氏估计量，用于估计存在多重共线性的参数向量，如果怀疑它属于线性子空间。导出了色散矩阵和均方误差(MSE)。新的估计器可能具有比传统估计器更低的MSE。通过仿真技术表明，在多重共线性情况下，新的收缩估计器优于常用的估计器。

A New Liu Type of Estimator for the Restricted SUR Estimator

A new Liu type of estimator for the seemingly unrelated regression (SUR) models is proposed that may be used when estimating the parameters vector in the presence of multicollinearity if the it is suspected to belong to a linear subspace. The dispersion matrices and the mean squared error (MSE) are derived. The new estimator may have a lower MSE than the traditional estimators. It was shown using simulation techniques the new shrinkage estimator outperforms the commonly used estimators in the presence of multicollinearity.
