(1 mark) If the sum of three positive residuals is 15 , what would be the sum of the negative residuals after fitting a least square regression line?
Question
Solution 1
In a least squares regression, the sum of the residuals, whether positive or negative, is always zero. This is because the regression line is fitted such that it minimizes the sum of the squared residuals. Therefore, if the sum of the positive residuals is 15, the sum of the negative residuals must Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
