Statistical dependence

a condition in which two random variables are not independent. X and Y are positively dependent if the conditional probability, P(X|Y), of X given Y is greater than the probability, P(X), of X, or equivalently if P(X&Y) >P(X).P(Y). They are negatively dependent if the inequalities are reversed
