Which of the followings is correct in a multiple linear regr

Which of the followings is correct in a multiple linear regression? Choose all correct answers.

a. Using Type I sums of squares, the order that variables enter into the model is not important.

b. In order to perform a multiple partial f-test, both Type I and Type III sums of squares are needed.

c. A test for the significance of each variable as it enters the model uses Type III sums of squares.

d. A test for the significance of each variable as added last to the model uses Type I sums of squares.

e. Both Type I sums of squares and Type III sums of squares produce the same sum of squares error.

Solution

Here statement in option d, statement in option e is also correct.

So option d and e are correct answers.
