For table I, compute support, the interest measure, and the ? correla- tion coefficient for the association pattern {A, B}. Also, compute the confidence of rules A ? B and B ? A.

Consider the contingency tables shown in Table 6.6.


s(A)=0.1, s(B)=0.9, s(A, B)=0.09.
I(A, B) = 9, ?(A, B)=0.89.
c(A ?? B)=0.9, c(B ?? A)=0.9.
