R-squared 值 一个从 0 到 1 之间的数字,显示趋势线的估算值与实际数据之间的对应关系。 当趋势线 R 平方值接近或接近 1 时,趋势线最可靠。 也称为决定系数。 在趋势预测中填写前推周期和后推周期,看看曲线对样本的预测情况: 可以看出,对数曲线对于样本的拟合和预测准确度相当有限。于是我们选择分段拟合,前段...
Now we can dive into the steps of calculating R-squared in Excel using theRSQfunction. How to Calculate R-squared in Excel In this section, we will explain the step-by-step process of calculating the R-squared in Excel using theRSQfunction. Furthermore, each step contains detailed instructio...

Instead, we recommended using the POWER() function to square, cube, or apply any raise to power to your cell. In our case, we have divided D2 by 100 to get height in meters and squared it by using the POWER() function with the second argument as 2. =POWER(D2/100,2) 6. ...
Multiple R-squared: 0.567, Adjusted R-squared: 0.5285 #决定系数R平方及修正R平方,R2表示模型拟合优度,越大越好 F-statistic: 14.73 on 4 and 45 DF, p-value: 9.133e-08 #F统计量为回归系数方差分析法里面的F统计量,越大越好,对应的P值越小越好 ...
