摘要
研究了广义回归系数模型中,回归系数的混合估计与LSE的相对效率,给出了上下界,并研究了加入附加信息前后β1*和β2*的相对效率。
Relative efficiencies of mixed estimator for generalized regression coefficients are studied. The lower and upper bounds of two relative efficiencies are obtained. And studied relative efficiency of β^＊1 and β^＊2 around the additional information.
