Log-evidence of the four models for experimental repressilator data.

The log-evidence computed by nested sampling for each model using the 60 experimental data points given in Figure 2C of the original repressilator paper [68]. The linear increase in fluorescence with time was removed and as the original data is in arbitrary units, it was rescaled the data to be maximally one. Using the interpretation given by Kass and Raftery [54] the use of experimental data now provides positive to strong evidence for the Schnakenberg model against the repressilator and very strong evidence against the other two models.
