纵向资料回归系数的新估计

A NEW ESTIMATOR OF REGRESSIONAL COEFFICIENT IN LONGITUDE DATA

本文研究纵向资料中回归系数的估计，借助于相依回归模型中的信息迭加法，给出了一个新估计，它改进了最小二乘估计．

In this paper,the authors study estimation of regressional coefficient in longitude data,Using information iteration in seemingly unrelated regression model,the authors give a new estimator which improves the least square estimator(LSE).
