基本解釋

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提供的函數(shù)LINEST和回歸分析工具進行線性回歸分析，并利用EXCEL的插入圖表功能做線性回歸擬合圖。也示例說明了線性回歸產(chǎn)生的測量不確定度的計算。
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).
簡單線性回歸建模背后的基本目標是從成對的 X值和 Y值（即 X和 Y測量值）組成的二維平面中找到最吻合的直線。
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.
提出一個求點集最佳直線的新方法，它能保證所有實驗點相對于最佳直線的最大偏差為最小。
