Quizplus · Accepted Answer

The degrees of freedom for SSE (Sum of Squares for Error) in a regression model is calculated as the total number of observations minus the number of parameters estimated (including the intercept). If the total number of observations is 25 and there are 6 parameters, the degrees of freedom would be 25 - 6 = 19.
