My implementation of a causal statistic was based on the measure of conditional mutual information proposed by Palus et al.(2001). The individual and joint entropies were estimated in the time domain by computing the corresponding correlation integrals, as proposed in
Prichard and Theiler (1995), and tested using linear and non-linear models, for example, in Chavez et al. (2003) and Vakorin et al. (2009). The significance of the results was tested with surrogate data generated by shuffling the phase in the Fourier domain (Theiler et al, 1992).
