Question

Quizplus · Accepted Answer

In a multiple regression analysis, the degrees of freedom associated with the sum of squared errors (SSE) is calculated as the number of observations minus the number of estimated parameters (including the intercept). With 40 data points and 4 explanatory variables plus an intercept, the degrees of freedom for SSE is 40 - (4 + 1) = 35.
