对半相依回归线性系统，我们周期地使用迭加信息的方法，得出了回归系数广义协方差改进估计。
In this paper we repeatedly draw information from the seemingly unrelated regression equations and introduce a method that can be used to improve the covariance improvement estimate (CIE).
来自回归线自身的数据可以用于提供线性程度的数学评估。
Data from the regression line itself may be helpful to provide mathematical estimates of the degree of linearity.
如果其呈现线性关系，测试结果应该通过适当的统计学方法(例如，以最小二乘方来计算回归线)来确立。
If there appears to be a linear relationship test results should be established by appropriate statistical methods (e. g. by calculation of a regression line by the method of least squares).
