Moreover, 100 synthetic EIS spectra were generated for each case. For all boxplots, the notch refers to the median, the box to the interquartile range, the circles to the outliers, and the whiskers to the interquartile range multiplied by 1.5. In the Bode plots, the means and 3 × 𝜎 credible bands for the real and imaginary parts of the impedance are shown as black lines and gray regions, respectively.
