Comments on and correction to "Axiomatic derivation of the principle of maximum entropy and the principle of minimum cross-entropy" (Jan 80 26-37) [Corresp.]

An error in the subject paper is pointed out: when the axioms given there are restricted to the discrete case, they do not imply the discrete case of the principle of minimum cross-entropy. The principle is shown to follow, however, from the adoption of an additional axiom: if new information is consistent with a prior estimate of a probability distribution, then the posterior estimate equals the prior. Minor other improvements and corrections to the arguments in the paper are made.
