best-fit line

基本解释

The LINEST technique, the regression tool and chart tool built in the EXCEL were used to generate a best-fit line and calculate relevant parameters as well as uncertainty.
用EXCEL提供的函数LINEST和回归分析工具进行线性回归分析，并利用EXCEL的插入图表功能做线性回归拟合图。也示例说明了线性回归产生的测量不确定度的计算。
The basic goal behind simple linear regression modeling is to find the line of best fit through a two-dimensional plane of paired X and Y values (that is, your X and Y measurements).
简单线性回归建模背后的基本目标是从成对的 X值和 Y值（即 X和 Y测量值）组成的二维平面中找到最吻合的直线。
A new method for the calculation of the best-fit line is presented. It can guarantee that the greatest vertical difference between experimental points and the best-fit line is a minimum.
提出一个求点集最佳直线的新方法，它能保证所有实验点相对于最佳直线的最大偏差为最小。
