%description
Models for non-linear time series analysis and causality detection. The
main functionalities of this package consist of an implementation of the
classical causality test (C.W.J.Granger 1980)
<doi:10.1016/0165-1889(80)90069-X>, and a non-linear version of it based
on feed-forward neural networks. This package contains also an
implementation of the Transfer Entropy <doi:10.1103/PhysRevLett.85.461>,
and the continuous Transfer Entropy using an approximation based on the
k-nearest neighbors <doi:10.1103/PhysRevE.69.066138>. There are also some
other useful tools, like the VARNN (Vector Auto-Regressive Neural Network)
prediction model, the Augmented test of stationarity, and the discrete and
continuous entropy and mutual information.
