Abstract: A nonextensive thermostatic approach to chaotic dynamical systems is developed by expressing generalized Tsallis distribution as escort distribution. We explicitly consider the thermodynamic limit and also derive the Legendre Transform structure. As an application, bit variance is calculated for ergodic logistic map. Consistency of the formalism demands a relation between box size (ε) and degree of nonextensivity, given as (1−q)∼−1/lnε. This relation is numerically verified for the case of bit variance as well as using basic definition of Tsallis entropy.
