Which of the following would be the least squares (best fitting) line?
The residual sum of squares is closest to zero
r is equal to zero
The residual sum of squares is closest to one
The variance of y is large
| a. | The residual sum of squares is closest to zero | |
| b. | r is equal to zero | |
| c. | The residual sum of squares is closest to one | |
| d. | The variance of y is large |
Solution
The residual sum of squares is closest to zero
because least squares line is calculated by minimizing residual sum of squares.
| a. | The residual sum of squares is closest to zero |
