WebIt is easy to see that if G 1 is comprised only of 2 variables, its integration is l o g ( 1 − ρ 2), which directly relates to the pairwise correlation coefficient of the variables ρ. To compute interaction between two groups of variables, you can use mutual information, which is just cross-entropy between the groups: M U 12 = I 12 − I 1 ... Web5.7. Correlation Coefficient. The correlation coefficient is a measure of the association between two variables when such association is linear. We calculate the correlation coefficient by centering and normalizing the variables: cor(xj,xk) = n ∑ i=1pi( xij − ¯xj sj)( xik − ¯xk sk) c o r ( x j, x k) = ∑ i = 1 n p i ( x i j − x ¯ j ...
