Simulations have shown that this estimator achieves higher accuracy and better confidence when compared with other methods. In this paper we present a rigorous study of the MAVAR log-regression estimator. In particular, under the assumption that the signal process is a fractional Brownian motion, we prove that it is consistent and asymptotically normally distributed. Finally, we discuss its connection with the wavelets estimators. %A Alessandra Bianchi %A Massimo Campanino %A Irene Crimaldi %K modified Allan variance, log-regression estimator, fractional Brownian motion, long-range dependence, self-similarity
