In a multiple linear regression (MLR) model mu = , what are the degrees of freedom for error (within)? a. 1 b. 2 c. 3 d. 4

Solution

There are three independent variables x1, x2 and x3 as regression equation is given as a linear combination of these 3.

Hence degrees of freedom for error (within)

= 3-1

= 2

Answer b is right.
