Abstract
The Renyi distribution ensuring the maximum of Renyi entropy is investigated for a particular case of a power-law Hamiltonian. Both Lagrange parameters and can be eliminated. It is found that does not depend on a Renyi parameter and can be expressed in terms of an exponent of the power-law Hamiltonian and an average energy . The Renyi entropy for the resulting Renyi distribution reaches its maximal value at that can be considered as the most probable value of when we have no additional information on the behavior of the stochastic process. The Renyi distribution for such becomes a power-law distribution with the exponent . When () there appears a horizontal head part of the Renyi distribution that precedes the power-law part. Such a picture corresponds to some observed phenomena.
