Tsallis statistics

From Wikipedia, the free encyclopedia

The term Tsallis statistics can refer to a number of things, but generally is used to describe the notion of probability distributions arising from the optimization of the Tsallis entropic form. A continuous real parameter q can be used to adjust the distributions so that distributions which have properties intermediate to that of Gaussian and Levy statistics can be created. This parameter q represents the degree of non-extensivity of the distribution. Tsallis statistics are useful for characterising complex, anomalous diffusion.
