How do we think about how well our sample regression line fits our sample data?
我们怎样衡量我们的样本回归线拟合样本数据有多好呢？
Data from the regression line itself may be helpful to provide mathematical estimates of the degree of linearity.
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。
The correlation coefficient y-intercept slope of the regression line and residual sum of squares should be submitted.
应该提交其相关系数、Y轴截距、回归线斜率、残差平方和。
Calculate the regression line of test results versus analyte concentrations. The correlation coefficient should be more than 0.99.
以测定结果的响应信号作为被测物浓度的函数作图，相关系数应大于0.99。
Based on the fact that total error is needed by the system, this thesis emphasizes particularly on analyzing the static regression line error model and its engineering feasibility.
侧重分析静态回归直线误差模型及工程应用的可行性，通过例证比较说明统计估算法的优势。
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).
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。
