由于系统方程是时变的，在测量过程中，系统噪声和观测噪声的统计特性等很难精确地估计或测定，事实上很多误差模型都不能简单的设为白噪声。

Compared with general statistic regression methods, this equation not only improves the interpretation precision, but also holds more reasonable geological significance.

该方程与普通的统计回归方法相比，既提高了解释精度，地质意义也更为合理。

One important summary value is a t statistic that can be used to measure how well a linear equation fits the data.

一个重要的汇总值是T统计值，它可以用来衡量一个线性方程与数据的吻合程度。
