Similarity measures for all datasets and all EDR signals with respect to rth(n). The indices n were removed to facilitate visualization, i.e., rth(n) = rth. The similarity between rth(n) and both rab(n) and rna(n) are indicated in the shaded boxes. *Indicate that ∣ρ∣ and \(\bar{{\gamma }_{r}}\) are significantly different for all EDR signals.
