causality index derived from this relation, which we term ’Topological Causality’, is analytically accessible for sim-ple systems and can be estimated in a model free, data driven manner for more complicated ones. We propose this measure as a suitable extension of the causality con-cept to non-separable dynamical systems. RESULTS

system (\no zt variables") the Granger causality concept is most straightforward to think about and also to test. By the way, be aware that there are special problems with testing for Granger causality in co-integrated relations (see Toda and Phillips (1991)). In summary, Granger causality tests are a useful tool to have in your toolbox, but ...

Then, since the Granger-causality test is very sensitive to the number of lags included in the regression, both the Akaike (AIC) and Schwarz Infor-mation Criteria have been used in order to find an appropriate number of lags. After that these requirements have been satisfied, Granger-causality tests are computed.

Causality Despite philosophic criticisms of inductive inference, inductively oriented causal criteria have commonly been used to make such inferences. If a set of ne-cessary and sufficient causal criteria could be used to distinguish causal from noncausal associations in observational studies, the job of the scientist would be eased considerably.
