Python Functions:
EntropyHub functions fall into 5 categories:
- Base
functions for estimating the entropy of a single univariate time series.
- Cross
functions for estimating the entropy between two univariate time series.
- Bidimensional
functions for estimating the entropy of a two-dimensional univariate matrix.
- Multiscale
functions for estimating the multiscale entropy of a single univariate time series using any of the Base entropy functions.
- Multiscale Cross
functions for estimating the multiscale entropy between two univariate time series using any of the Cross-entropy functions.
When new entropies are published in the scientific literature, efforts will be made to incorporate them in future releases.
Important
For concision, function commands written in the following sections using Python syntax exclude the module prefix which would otherwise be required,
i.e. EntropyHub.SampEn()
is written as SampEn()
.
Note
Python functions in EntropyHub are based primarily on the Numpy package.
Arguments shown in python functions with the np.
prefix refer to numpy functions.
