From correlation to causation: Estimating effective connectivity from zero-lag covariances of brain signals
Fig 7
Comparison of performance with the Regularized Inverse Covariance (RIC) method based on numerical simulations of Ornstein-Uhlenbeck processes.
Shown are the results from the reconstruction of 20 different networks with Erdős-Rényi connectivity profiles as described before (cf. Fig 2). AUC, PRS and PCC of our new method and of the RIC method, respectively, are shown side-by-side.
