Ditching causality

Causality

Causality, Conditional Exogeneity, and Granger Causality

We relate notions of structural causality and conditional exogeneity as de…ned in White and Chalak (2006) (WC) to the concept of Granger causality. We show that given conditional exogeneity, structural non-causality implies retrospective Granger non-causality, an extension of the classical Granger (1969) non-causality condition. We also provide a form of converse to this result and tests for re...

K-causality coincides with stable causality

It is proven thatK-causality coincides with stable causality, and that in a K-causal spacetime the relation K coincides with the Seifert’s relation. As a consequence the causal relation “the spacetime is strongly causal and the closure of the causal relation is transitive” stays between stable causality and causal continuity.

Visualizing Causality

The Temporal Network Visualizer is an experimental system to perform real-time visualization of time varying network oriented data. It builds upon the concept of stripcharts to augment a user's memory of past events, enhancing the user's ability to recognize patterns that occur across time as well as space, patterns that we associate with causality. Examples are given for visualizing transactio...

Structural Causality

Using quantum entanglement as a simple model of correlations between two systems, one can show that a new causal category must be incorporated into any complete description of physical reality. Such “structural causality” is related to the structural properties of the product space underlying a functional description of a multipart entity. Aristotelian causal categories and the restricted deriv...
