Dependent Variable: It is also known as the response variable or outcome variable, it is the variable predicted or explained by the regression model. It is denoted as Y. Independent Variable: It is referred to as the predictor variable or explanatory variable, it is the variable used to predi...
In a simple linear regression situation, the ANOVA test is equivalent to thettest reported in the Parameter Estimates table for the predictor. The estimates in the Parameter Estimates table above are the coefficients in our fitted model. As we have discussed, we can use this model directly...
Example 2 – Interpreting Regression Results of ANOVA Table in Excel In the middle of the output, you’ll see the ANOVA (Analysis of Variance) Table. The terms used in the table are as follows. df (degrees of freedom): df refers to degrees of freedom. It can be calculated using the ...

It includes the Sum of Squares table, and the F-test on the far right of that section is of highest interest. The “Regression” as a whole (on the top line of the section) has a p-value of less than 0.0001 and is significant at the 0.05 level we chose to use. Each parameter sl...
Table 13.5-1. Solver regression results for 104 monthly returns for a fund versus its benchmark. SSE(SumofSquaredErrors)=∑t=1T=104(Yt−Yˆt)2(UnexplainedVariation) RSS(RegressionSumofSquares)=∑t=1T=104(Yˆt−Y¯)2(ExplainedVariation) TSS(TotalSumofSquares)=∑t=1T=104(Yt−Y...
SSregression – Explained sum of squares due to the regression model. SStotal – The total sum of squares. The sum of squares due to regression assesses how well the model represents the fitted data and the total sum of squares measures the variability in the data used in the regressio...
The GWR tool also produces Output Features values and adds fields reporting local diagnostic values. The Output Features values and associated charts are automatically added to the table of contents with a hot/cold rendering scheme applied to model residuals. A full explanation of each output ...
Run a Multiple Regression on Fertility using all of the other variables as predictors. Print the model and coefficients table. Explain the meaning of the significant coefficients. Check the assumptions using the diagnostic tests mentioned in this section. Discuss your findings. ...
