fathon
is only available for Linux (64 bit) and macOS
fathon
is a python package for DFA (Detrended Fluctuation Analysis) and related algorithms.
It is mostly written in Cython and C in order to speed up computations.
fathon
provides four main algorithms, namely
DFA
(Detrended Fluctuation Analysis)MFDFA
(Multifractal Detrended Fluctuation Analysis)DCCA
(Detrended Cross-Correlation Analysis)HT
(Time-dependent Hurst exponent)
MFDFA
also provides methods for the mass exponent τ and the multifractal spectrum f(α).
DCCA
has methods for computing the cross-correlation coefficient ρ_DCCA and the corresponding confidence intervals.
-
Python 3.5 or higher
-
numpy (version >= 1.15)
-
Cython
As easy as pip install fathon
A jupyter notebook can be used (fathon_example.ipynb
) to play with the four algorithms provided by the fathon
package.
If you cannot use the notebook, four Python scripts are provided, dfa.py
, mfdfa.py
, dcca.py
, and ht.py
.
Algorithms are implemented on two time series of gaussian white noise, but you can replace them with any time series you like.
