Critique of multinomial coefficients method for evaluating Tsallis and Rényi entropies

Oikonomou [Th. Oikonomou, Physica A 386 (2007) 119] has published a calculation which purports to show that the Tsallis and Rényi entropies can be obtained from the generalized multinomial coefficients. In this paper, we prove that the method of generalized multinomial coefficients failed to determine the Tsallis entropy at equilibrium. Moreover, it is shown that Oikonomou’s analysis contains mistakes which led to misleading statements related to the Jaynes principle of maximum entropy, the Tsallis and the Rényi statistics.
