Conditional dispersion to detect causality between chaotic time series

Causality detection using calculation of distances in Takens's spaces

the package contains files for testing a conditional dispersion method
to detect causality relations between time series
-cd_tst_henon_map.m runs the test based on coupled Henon maps
-henon_map.m - equations of coupled Henon maps by Cenys et al.,(1991)

-cd_tst_VdP.m runs the test based on coupled Van der Pol equations.
-VdP.m - function to calculate coupled Van der Pol equations (dos Santos et al., 2004)

-nlincor.m - the basic function to calculate conditional dispersion by Cenys et al.,(1991)

-taks.m is the function to calculate the Takens's space from the observable time series.
