Example 3 – Interpreting Results of Multiple Regression Coefficients Table in Excel Coefficients: Coefficients are calculated using the least square method. In this example, the regression equation will be- y(Sales)=-1642.04 + 9.91*Unit Price + 8.13*Promotion Standard Error: It is the standard...
We get the following coefficients from the table above.α0= 43.11,α1= – 0.82,α2= 2.42, andϵ = 6.58. Therefore, the equation becomes: Y = 43.11 – 0.82X1+ 2.42X2+ 6.58 Method 2 -Multiple Linear Regression with the LINEST Function ...

每次做回归(regression)的时候,只用一年的数据,例如:Y是2005年的stock return,X是2005年的NIit,2005年的Qit,2005年的LEVit,等等等等(X要用到除了stock return之外的那些数据)。我用excel做的时候,一旦选择了多个X进行回归(regression)的时候,... 展开 匿名...

比如：A1为a值，B1为b值，C1为C值，D1为X值，最后结果为E1。接着你在菜单里找出“插入--图表”，其中有柱形的，折线形的，饼图的，散点形的等等。你可以选择折线形的，点击折线形图表，会出现相应的对话框（因为不知道楼主用的是什么版本，所以在这里只有笼统的说明），在里面添加“最后结果为E1...

Multicollinearity does not reduce the overall predictive power of the model but it can cause the coefficients of the independent variables in the regression equation to change erratically when small changes are introduced to the regression inputs. Multicollinearity can drastically reduce the validity of ...
I did a multiple regression in excel, where multiple R is 0.82, p values of all coefficients well below 0.05 only the intercept p value is 0.62. All VIF is less than 3, so there is no multicolinearity. Why the p value of intercept is high? Can I use the model?
