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 ...
Therefore, the equation becomes: Y = 43.11 – 0.82X1 + 2.42X2+ 6.58 Method 2 -Multiple Linear Regression with the LINEST Function Alternatively, you can utilize the LINEST function in Excel to obtain regression results. Follow these steps: Enter the Formula: In cell H5, enter the ...
How To Run A Multiple Regression In Excel And Actually Understand The ResultsSara Silverstein
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 | 浏览2948 次 |举报 我有更好的答案推荐于2017-12-...

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?
