Abstract

The paper that is commented by Touchette contains a computational study which opens the door to a desirable generalization of the standard large deviation theory (applicable to a set of NN nearly independent random variables) to systems belonging to a special, though ubiquitous, class of strong correlations. It focuses on three inter-related aspects, namely (i) we exhibit strong numerical indications which suggest that the standard exponential probability law is asymptotically replaced by a power-law as its dominant term for large NN; (ii) the subdominant term appears to be consistent with the qq-exponential behavior typical of systems following qq-statistics, thus reinforcing the thermodynamically extensive entropic nature of the exponent of the qq-exponential, basically NN times the qq-generalized rate function; (iii) the class of strong correlations that we have focused on corresponds to attractors in the sense of the Central Limit Theorem which are QQ-Gaussian distributions (in principle 1<Q<31 < Q < 3), which relevantly differ from (symmetric) L\'evy distributions, with the unique exception of Cauchy-Lorentz distributions (which correspond to Q=2Q = 2), where they coincide, as well known. In his Comment, Touchette has agreeably discussed point (i), but, unfortunately, points (ii) and (iii) have, as we detail here, visibly escaped to his analysis. Consequently, his conclusion claiming the absence of special connection with qq-exponentials is unjustified.
