Abstract :
We give a necessary, sufficient, and easily verifiable criterion for the conditional probability distribution PZ|XY (where X, Y and Z are arbitrary random variables), such that I(X; Y)≥I(X; Y|Z) holds for any distribution PXY. Furthermore, the result is generalized to the case where Z is specified by a conditional probability distribution depending on more than two random variables.
