Scatter plots that relate PF estimates (x axis) and true values (y axis) of the autoregressive model for a 6-node network with 100 time samples, in the absence of noise (left) and with \(\hbox {SNR} = 6\,\hbox {dB}\) (right). The lines are the results of a linear fit of the data: in the noiseless case the slope m and the offset q were 1.39 and \(-1.62\cdot 10^{-2}\), respectively; in the noisy case, \(m = 1.62\) and \(q = 8\cdot 10^{-3}\)
