Logarithmic Bayes factor for a four-point TP profile vs. an isothermal profile. The figure shows in blue the value obtained with nonrandomized spectra, and green dots represent the 20 values for normally distributed noisy spectra (30 ppm standard deviation). The logarithmic Bayes factor averaged on the 20 simulations is shown in light green. The nonrandomized logarithmic Bayes factor and its noisy average counterpart are almost identical, proving that our study can be based on nonrandomized spectra.
