1．首先，我们打开一个excel文档并选择数据进行演示，如下图所示。2．选择要分析的数据后，点击“插入”，选择“散点图”，选择散点图类型。3．在选项框中，选择趋势线“linear”，勾选“showformula”和“showRsquaredvalue”，点击“close”。4．此时，从图中可以看出，线性相关系数R的平方为0．9924...
Luckily, we can simply use theRSQfunction in Excel to find the R-squared value of our data set. And the value for R-squared only range from zero to one. So a value of 0 can conclude that the predictor variable cannot explain the response value at all. Additionally, an r-squared value...

The residuals are normally distributed with zero mean and variance σ2 (spoken as ‘sigma-squared’). This assumption is often written in shorthand as εi ~ N(0,σ2 ) ... [正态分布] The variance of the residuals is constant, whatever the value of x. This means that if we take ...
