... entropy and marginal guesswork have nothing to do with each other in the sense that there is no general inequality relating them one to the other. Let X be a random variable taking values in the alphabet ... visiting x and 0 afterwards. This is possible only if x>0, since otherwise {S k } k≥0 must attain 0 again. So if I =0,thenP (ξ(x)=k, ρ = ∞) = 0.
