If the value of the sum of squares for error SSE equals zero,then the coefficient of determination must equal zero.

Question

Quizplus · Accepted Answer

If the value of SSE equals zero, it means that the regression line perfectly fits all the data points and explains all the variability in the data. In this case, the coefficient of determination, also known as R-Squared, would equal 1, not 0. R-Squared measures the proportion of variability in the dependent variable that is explained by the independent variable(s) in the regression equation. So, if SSE is zero, R-Squared would be 1, not 0.
