mean value of the conditional information content of the events in a finite set of mutually exclusive and jointly exhaustive events, given the occurrence of the events in another set of mutually exclusive and jointly exhaustive events; in mathematical notation, this measure is H(X|Y) = [...][...] p(xi,yj)l(xi|yj) where X = {x1 ... xn} is the set of events xi (i = 1 ... n), Y= {y1 ... ym} is the set of events yi = (1 ... m), l(xi|yj) is the conditional information content of xi given yj, and p(xi,yj), the joint probability that both events occur
