Question: Let X(i) be the design matrix with the ith row removed. Why is it true that a. It is not true at all b. Because

Let X(i) be the design matrix with the ith row removed. Why is it true that

XX) = X X-XX! n xx = Exx; j=1 where x is

a. It is not true at all

b. Because the jth data row. xx = 2xx j=1 where x is the c. Because

jth data row. xx = 2 x x j=1 where x is

d. Because

the jth data column. P xx = 2xx < j=1 where x

e. Because

is the jth data column.

XX) = X X-XX! n xx = Exx; j=1 where x is the jth data row. xx = 2xx j=1 where x is the jth data row. xx = 2 x x j=1 where x is the jth data column. P xx = 2xx < j=1 where x is the jth data column.
