Details of the experimental data sets used in this paper have been given previously in. In summary, large amplitude ac voltammetry was performed in a standard three-electrode cell, using a glassy carbon macrodisk (diameter 3 mm) working electrode. All potentials are reported versus an Ag/AgCl/KCl(3 M) reference electrode (hereinafter Ag/AgCl). The frequencies, amplitude and scan rate were 9.02 Hz, 0.080 V and 0.894 Vs -1 respectively and data were collected over the potential range of 0.5 to -0.1 V versus Ag/AgCl. The surface area of the electrode was estimated as 0.070 cm 2 . The value of the diffusion coefficient, D, of [Fe(CN) 6 ] 3-was found to be 7.2 × 10 -6 cm 2 s -1 , as described in. In this paper we make use of the ten repeated data sets for ac voltammetry taken from for the reduction of aqueous 1.0 mM [Fe(CN) 6 ] 3-in 3 M KCl aqueous electrolyte solution. In order to reduce the amount of computation required for the parameter inference, we use a moving average window of length 21 to reduce the number of experimental data points within each data set to about 25,000 data points.
