Comment on "Universal and accessible entropy estimation using a compression algorithm"
E. Brigatti, F. N. M. de Sousa Filho
In a recent Letter [1] a framework for estimating entropy was introduced and applied to one-dimensional and two-dimensional systems. In this Comment we show that the method is not…
Entropy estimation in bidimensional sequences
F. N. M. de Sousa Filho, V. G. Pereira de Sá, E. Brigatti
We investigate the performance of entropy estimation methods, based either on block entropies or compression approaches, in the case of bidimensional sequences. We introduce a vali…
Entropy and hierarchical clustering: characterising the morphology of the urban fabric in different spatial cultures
E. Brigatti, V. M. Netto, F. N. M. de Sousa Filho +1
In this work, we develop a general method for estimating the Shannon entropy of a bidimensional sequence based on the extrapolation of block entropies. We apply this method to anal…
The leverage effect and other stylized facts displayed by Bitcoin returns
F. N. M. de Sousa Filho, J. N. Silva, M. A. Bertella +1
In this paper, we explore some stylized facts of the Bitcoin market using the BTC-USD exchange rate time series of historical intraday data from 2013 to 2020. Bitcoin presents some…
