Non-linear auto-regressive models for cross-frequency coupling in neural time series

Estimating delays over 20 simulations for each delay.
The delays are estimated on both direct time (a) and reverted time (b). The delays are normalized: τ = 1 corresponds to one driver oscillation, i.e. 1/fx sec. The modified CFD shows a bias and only serves for qualitative comparison. The delay estimation based on DAR models correctly estimates the delays, with no visible bias.
