Revisiting the volatility of bitcoin with approximate entropy
Cogent Economics & Finance, 2022 Two distinct and non-redundant understandings of volatility, as deviation from consistency, exist for a time-series: (1) exhibiting high standard deviation and, closer to the dictionary definition of the term, (2) appearing highly irregular and ...

ON APPROXIMATION OF MEASURES OF MAXIMAL ENTROPY
Far East Journal of Dynamical Systems, 2013 For a class of non-invertible hyperbolic dynamical systems Mihailescu has introduced probability states describing the distribution of preimages. These states converge to a measure of maximal entropy. Here we consider Anosov endomorphisms and show that for systems semi-conjugated to them can be constructed measures describing consecutive preimages and ...
