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 ...
Next are the regression coefficients of the model (‘Coefficients’). Row 1 of the coefficients table islabeled(Intercept) – this is the y-intercept of the regression equation. It’s helpful to know the estimated intercept in order to plug it into the regression equation and predict values o...
Multiple Regression Multiple Regression is a special kind of regression model that is used to estimate the relationship between two or more independent variables and one dependent variable. It is also called Multiple Linear Regression(MLR).
All the other entries can be calculated in a manner similar to how we calculated the ANOVA values for Example 1 ofTesting the Fit of the Regression Line(see Figure 1 on that webpage). Coefficients(in the third table) – we show how to calculate the intercept fields; the color and quali...
Confidence intervals and hypothesis tests for an individual regression coefficient will be based on its standard error, Sb1, Sb2,…, or Sbk. The critical value from the t table will have n − k − 1 degrees of freedom. Inference is based on the multiple regression linear model, which ...
The first table of interest is the Model Summary table. This table provides the R, R2, adjusted R2, and the standard error of the estimate, which can be used to determine how well a regression model fits the data: Published with written permission from SPSS Statistics, IBM Corporation. The...
ANOVA Table Analysis of variance(ANOVA) is a statistical procedure that provides information on the explanatory power of a regression. The result of the ANOVA procedure are presented in an ANOVA table, which accompanies with the output of a multiple regression program. An example of a generic ANO...

When interpreting the results of multiple regression, beta coefficients are valid while holding all other variables constant ("all else equal"). The output from a multiple regression can be displayed horizontally as an equation, or vertically in table form. ...
