Abstract: | In addition to the comparison of the Gibbs negentropy ηG = ∫ Π ln Π to the Shannon negentropy ηs = ∑ EiΠi ln(EiΠi), discussed in the cited paper, a comparison of the former to ηs′=ηs?∑E i lnE i the decrease in uncertainty, is of general interest from an information-theoretic standpoint. It is shown that ηG and ηs′ are similar in the situation in question. The additivity properties of ηG are briefly discussed. |
