Confounding Effects of Indirect Connections on Causality Estimation

[...]the connectivity map obtained using the partial statistic depends on the number of variables included in the model: (b) with all eight sources; (c) with the "unobserved" source #7. [...]we considered the problem of model misspecification and its effect on the robustness of the observe...

Description
Summary:[...]the connectivity map obtained using the partial statistic depends on the number of variables included in the model: (b) with all eight sources; (c) with the "unobserved" source #7. [...]we considered the problem of model misspecification and its effect on the robustness of the observed connectivity patterns, showing that misspecifying the model may be an issue even for a model-free information-theoretic approach.
