Abstract :
We propose confidence intervals for the conditional coherence using the bootstrap. The asymptotic distribution of the empirical conditional coherence is inaccurate when signal and noise are non-Gaussian and/or the data size is small. The confidence intervals obtained with the bootstrap are shown to be accurate, maintaining the preset level of confidence.
