The sum of the squared errors or residuals is a scalar, a single number. In matrix form, the estimated sum of squared errors is: (10) where the dimensions of each matrix are shown below each matrix and the symbol represents the matrix transpose operation. The following example illustrates why this definition is the sum of squares.

Introduction - Springer
F-value is calculated using explained sum of squares and regression sum of squares. However one need to look at the p-value of F-statistic to make the final inference about acceptance of the model. If the p-value F-test is less than 5% then we reject null hypothesis H 0 , i.e we reject the hypothesis that the model has no explanatory power.

R squared tells us the percentage of variation in y that is explained by our model. We know that R squared = Explained Sum of Squares/Total Sum of Squares. Thus, the Explained Sum of Squares is equal to 82% of the Total Sum of Squares. Problem 2. 2.1. e) X is the number of years of education. Thus, it is a quantitative variable.

The model sum of squares is partitioned into two parts. The model sum of squares is partitioned into three parts. The correct answer is d) The model sum of squares is partitioned into three parts. Feedback: The model sum of squares is partitioned into the effect of each of the independent variables and the effect of how these variables interact.

Add all those errors-squared together. Call this SSE (sum of squared errors) Use DDXL or another statistics package to find the variance of your Y-values and multiply that number by (number of pairs –1) so that you have SSY (sum of squares for Y). Calculate (1 – (SSE/SSY))*100 % as the percent of variation explained.

The third definition is the residual sum of residuals (errors) (SSE), which was earlier defined as: (21) SSE is the amount of variation not explained by the regression equation. It be shown the total sum of the variation in y around its mean is equal to the amount of variation in y around its mean plus the amount of variation not explained.
