摘要
研究了无约束的线性模型M={Y,X(,(2V}的最小二估计ＯＬＳＥ与在相应的有约束的线性模型Mr={Y,X(|R'(=0,(2Ｖ}下Ｘ(的最佳线性无偏估计ＢＬＵＥ(Ｘ()的比较问题，建立了在Ｍｒ下这两个线性无偏估计量相等的充要条件．
A relationship is studied between the OLSE of under a general unrestricted linear model and the BLUE of under the corresponding restricted modelNecessary and sufficient conditions are obtained for the OLSE of under M to be also theBLUE of under Mr.
